== ULF Wave Modeling Challenge ==

We're organizing a modeling challenge to investigate the ability of global models to reproduce ULF wave fields in the magnetosphere, and ultimately if those ULF fields can radially diffuse an existing electron population from L~5.5 to L~4.5 in two weeks.

1. Can global models of the magnetosphere reproduce the observed persistent, solar wind driven, low mode number ULF wave fields in the magnetosphere?

2. Are those waves capable of producing the observed energetic radiation belt population evolution observed during the first two weeks of March 2013 as observed by Van Allen Probes?

[[Image:radialDiffusionInterval.png]]

The figure above is the REPT flux from http://www.rbsp-ect.lanl.gov/science/LTPlots/RBSP-ECT_LT_Mission_plot.pdf with the interval I mentioned circled in pink. Tick marks in time (x-axis) are one month in duration. The modest electron belt which starts out at L~5.5 seems to diffuse inward a whole L in two weeks. I would think that a key aspect of that question which MHD models could uniquely constrain is the fraction of the diffusion which is accomplished by solar wind driving alone.

'''Metrics and Validation Focus Group'''
'''Status Report'''

''Current Co-Chairs (2005-2012): Masha Kuznetsova (CCMC), Aaron Ridley (Univ. of Michigan).
New Co-Chairs (2012-2015); Tim Guild (Aerospace Corp), Lutz Rastaetter (CCMC), Howard Singer (NOAA)''

In summer 2008 the GGCM Metrics and Validation Focus Group initiated the GGCM modeling Challenge. The goals of the Challenge:

• Evaluate the current state of the space science models and track model improvements over time

• Facilitate interaction between research and operation communities

• Facilitate collaboration among modelers and data providers and research communities.

• Facilitate further model improvement.

The project focuses on various scientific and operational aspects of GGCM model performance and addresses challenges of model-data comparisons and metrics studies (e.g., model output and observational time series preparation for comparison, measurement uncertainty, metrics selection).

The following model/data comparisons (Matrics Studies) are involved in the Modeling Challenge:

Metric Study 1: Magnetic field at geosynchronous orbit (GOES)

Metric Study 2: Magnetopause crossings by geosynchronous satellite (GOES and LANL)

Metric Study 3: Plasma density/temperature at geosynchronous orbit (LANL)

Metric Study 4: Ground magnetic perturbations (ground based magnetometers)

Metric Study 5: Dst index (added at 2009 summer workshop)

Metric Study 6: Heat flux into ionosphere (added at 2010 summer workshop)

Metrics Study 7: Auroral oval position (study of interest to US Airforce, details to be discussed at fall 2010 mini-workshop)

Four events were selected at the GEM 2008 Workshop:

Event 1: Oct 29, 2003 06:00 UT - Oct 30, 06:00 UT (Kp = 9, Dst_min=-353nT)

Event 2: Dec 14, 2006 12:00 UT - Dec 16, 00:00 UT (Kp = 8, Dst_min=-139nT)

Event 3: Aug 31, 2001 00:00 UT - Sep 01, 00:00 UT (Kp = 4, Dst_min=-40nT)

Event 4: Aug 31, 2005 10:00 UT - Sep 01, 12:00 UT (Kp = 7, Dst_min=-131nT)

Two more events were added in summer 2010 for metrics study 6 on request of Dayside FAC and Energy Deposition focus group:

Event 5: May 15, 2005 00:00 UT - May 16, 2005, 00:00 UT

Event 6: July 9, 2005 00:00 UT - July 12, 2005, 00:00 UT

'''[http://gem.epss.ucla.edu/mediawiki/pdf/status.pdf Status of on-going metrics studies and future plans:]'''

1) Ground magnetic perturbations and magnetic field at geosynchronous orbit.
The first results of metrics studies 1 and 4 discussed at GEM 2009 and 2010 summer workshops are available at the CCMC website and at the GEM wiki. Two papers (with all Challenge participants as co-authors) are submitted to the Space Weather Journal.
Pulkkinen, A., M. Kuznetsova, A. Ridley, J. Raeder, A. Vapirev, D. Weimer, R. Weigel, M. Wiltberger, G. Millward8, L. Rastaetter, M.Hesse, H. J. Singer and A. Chulaki, GEM 2008-2009 Challenge: ground magnetic field perturbations, submitted to Space Weather Journal, 2009
Rastatter, L., M. M. Kuznetsova, A. Vapirev, A. Ridley, V. G. Merkin,
A. Pulkkinen M. Hesse, H. J. Singer, GEM 2008-2009 Challenge: magnetic fjelds at geosynchronous satellite positions, submitted to Space Weather Journal, 2010.
The principal conclusion of these studies is that ranking of the models is strongly dependent on the type of metric (the way how observational and modeled time series are compared) used to evaluate the model performance. Type of metrics to be used depends on the application and should be defined by model science and operational users. Metrics 4 is suggested for the Operational Metrics by NOAA SWPC. On NOAA SWPC request metrics format will be modified to focus on regional Kp and dB/dt. CCMC is working with the community to develop an automated system that will allow repeating the exercise on regular basis. We will continue dialog with the operations community to refine the metrics format. The second round of model-data comparison is planned for spring 2012 with the first report on model improvement over time to be presented at 2012 2ummer workshop.

2) Plasma parameters at the geosynchronous orbit.

To proceed with the study SOPA ion corrections for MPA are needed for pressure comparison. A group of LANL scientists are working on removal of electron contamination from the low- energy ion channels of SOPA. We exxpected completion of the first round of model-data comparison before the end of 2012.

3) Magnetopause crossings by geosynchronous satellite.

Preliminary analysis of Challenge results demonstrated significant differences between observations and model predictions. The unexpected result is that magnetopause standoff distance varies significantly for different global MHD codes. To address the issue in more details we initiated baseline model comparison study, when researchers run different MHD codes with different settings for various solar wind and IMF conditions and compare the results.
Preliminary analysis of the results at 2010 summer workshop excluded a number of possible sources for disagreement (e.g., such as grid resolution or value of anomalous resistivity). The latest idea is that the most likely source for the discrepancies are differences in inner boundary conditions. The decision was made to continue the study with the goal to resolve the issue within the next two years. We plan to initiate collaborations on this topic with FGs in magnetopause research area and with FG magnetic reconnection.

4) Dst index.

The Dst index Challenge originated in summer 2009 is a joint project with Inner Magnetisphere Focus group (liaison Dan Welling). The preliminary results were discussed at 2010 summer workshop. Report on the first round of study will be presented at the fall 2010 mini-workshop. Different ways of Dst index calculations are currently being analyzed. We plan to finalize the paper to be submitted to the Space Weather Journal before the summer workshop 2011.

5) Heat flux into ionosphere.

Heat flux into ionosphere metrics study was initiated in summer 2010. This is a joint project with Dayside FAC and Energy Deposition focus group (liaison Stefan Eriksson). The study involves comparison with Poynting flux time series derived from DMSP observations. To facilitate the research two additional events were added to the original four GEM events. This study is of potential interest to CEDAR community (as was agreed at the CEDAR 2010 summer workshop). Simulations, data preparation, and tool development for model output postrocessing are currently on the way. We plan to present the first results for the discussion at summer workshop 2011. We expect this project to continue until the end of 2012 and beyond.

6) Auroral oval position.

In summer 2010 we agreed on the importance to include auroral oval position metrics study. This metrics study is of primary interest to a number of GGCM model operational users including US Air Force. This study is also of a potential interest to the CEDAR community. The discussion on the details of this challenge is planned for the fall 2010 mini Workshop. We plan to continue this study beyond 2012.

'''Joint GEM-CEDAR Challenge'''

To analyze the effects geospace environment on the ionosphere we are planning to involve CEDAR Community to the Modeling Challenge. This activity is especially relevant due to upcoming joint GEM-CEDAR Workshop in 2011. Preliminary discussion with ionosphere modelers at CEDAR was held at CEDAR 2009 and 2010 Workshops. GEM M&V FG co-chairs were involved in the organizing of the CEDAR Electrodynamics-Thermosphere-Ionosphere Challenge. CEDAR modelers included GEM challenge events for the series of planned comparative studies. Further, many of the magnetospheric models are coupled to ionosphere-thermosphere models, therefore, the metrics can be conducted for both coupled and uncoupled simulations on both models.

'''Baseline model comparison'''

An aspect of validating models is to determine how well they solve the equation set that they are supposed to be solving. This type of validation has to do with checking the numerics of the codes. The method in which this validation will be conducted is to have researchers run different MHD codes for various solar wind and IMF conditions and compare the results. For this, we have requested that modelers run a time period in which the solar wind stays constant at 5/cc and -400 km/s, while the IMF Bz drops every few hours from -5, -10, -20, -30, -35, to -40 nT. The ionospheric conductance was held constant at 5 mhos. Another series of runs will change the solar wind ram pressure, while keeping the IMF Bz equal to – 10 nt. Initial simulation results were presented at 2009 and 2010 summer workshops. It was shown that many of the models had significant differences. It was decided upon that the subsolar magnetopause location, the cusp location, and the current structures at the magnetopause will be investigated under the different IMF conditions. Further investigations will include (1) examining the reconnection rate in the different codes to determine how each handles reconnection for the different IMF orientations; (2) examining the tail length, the amount of open flux in the polar caps and the plasma sheet density during the different intervals;
(3) the cross polar cap potential; and (4) the Dst as a function of time. With these types of comparisons, the GGCM Metrics and Validation Focus Group can collaborate with other focus groups within the GEM community. It is expected that the FG will arrange a special issue of a journal to capture the results of these comparisons.

2. Are those waves capable of producing the observed energetic radiation belt population evolution observed during the first two weeks of March 2013 as observed by Van Allen Probes?

Tick marks in time (x-axis) are one month in duration. The modest electron belt which starts out at L~5.5 seems to diffuse inward a whole L in two weeks. I would think that a key aspect of that question which MHD models could uniquely constrain is the fraction of the diffusion which is accomplished by solar wind driving alone.

'''Metrics and Validation Focus Group'''
'''Status Report'''

''Current Co-Chairs (2005-2012): Masha Kuznetsova (CCMC), Aaron Ridley (Univ. of Michigan).
New Co-Chairs (2012-2015); Tim Guild (Aerospace Corp), Lutz Rastaetter (CCMC), Howard Singer (NOAA)''

In summer 2008 the GGCM Metrics and Validation Focus Group initiated the GGCM modeling Challenge. The goals of the Challenge:

• Evaluate the current state of the space science models and track model improvements over time

• Facilitate interaction between research and operation communities

• Facilitate collaboration among modelers and data providers and research communities.

• Facilitate further model improvement.

The project focuses on various scientific and operational aspects of GGCM model performance and addresses challenges of model-data comparisons and metrics studies (e.g., model output and observational time series preparation for comparison, measurement uncertainty, metrics selection).

The following model/data comparisons (Matrics Studies) are involved in the Modeling Challenge:

Metric Study 1: Magnetic field at geosynchronous orbit (GOES)

Metric Study 2: Magnetopause crossings by geosynchronous satellite (GOES and LANL)

Metric Study 3: Plasma density/temperature at geosynchronous orbit (LANL)

Metric Study 4: Ground magnetic perturbations (ground based magnetometers)

Metric Study 5: Dst index (added at 2009 summer workshop)

Metric Study 6: Heat flux into ionosphere (added at 2010 summer workshop)

Metrics Study 7: Auroral oval position (study of interest to US Airforce, details to be discussed at fall 2010 mini-workshop)

Four events were selected at the GEM 2008 Workshop:

Event 1: Oct 29, 2003 06:00 UT - Oct 30, 06:00 UT (Kp = 9, Dst_min=-353nT)

Event 2: Dec 14, 2006 12:00 UT - Dec 16, 00:00 UT (Kp = 8, Dst_min=-139nT)

Event 3: Aug 31, 2001 00:00 UT - Sep 01, 00:00 UT (Kp = 4, Dst_min=-40nT)

Event 4: Aug 31, 2005 10:00 UT - Sep 01, 12:00 UT (Kp = 7, Dst_min=-131nT)

Two more events were added in summer 2010 for metrics study 6 on request of Dayside FAC and Energy Deposition focus group:

Event 5: May 15, 2005 00:00 UT - May 16, 2005, 00:00 UT

Event 6: July 9, 2005 00:00 UT - July 12, 2005, 00:00 UT

'''[http://gem.epss.ucla.edu/mediawiki/pdf/status.pdf Status of on-going metrics studies and future plans:]'''

1) Ground magnetic perturbations and magnetic field at geosynchronous orbit.
The first results of metrics studies 1 and 4 discussed at GEM 2009 and 2010 summer workshops are available at the CCMC website and at the GEM wiki. Two papers (with all Challenge participants as co-authors) are submitted to the Space Weather Journal.
Pulkkinen, A., M. Kuznetsova, A. Ridley, J. Raeder, A. Vapirev, D. Weimer, R. Weigel, M. Wiltberger, G. Millward8, L. Rastaetter, M.Hesse, H. J. Singer and A. Chulaki, GEM 2008-2009 Challenge: ground magnetic field perturbations, submitted to Space Weather Journal, 2009
Rastatter, L., M. M. Kuznetsova, A. Vapirev, A. Ridley, V. G. Merkin,
A. Pulkkinen M. Hesse, H. J. Singer, GEM 2008-2009 Challenge: magnetic fjelds at geosynchronous satellite positions, submitted to Space Weather Journal, 2010.
The principal conclusion of these studies is that ranking of the models is strongly dependent on the type of metric (the way how observational and modeled time series are compared) used to evaluate the model performance. Type of metrics to be used depends on the application and should be defined by model science and operational users. Metrics 4 is suggested for the Operational Metrics by NOAA SWPC. On NOAA SWPC request metrics format will be modified to focus on regional Kp and dB/dt. CCMC is working with the community to develop an automated system that will allow repeating the exercise on regular basis. We will continue dialog with the operations community to refine the metrics format. The second round of model-data comparison is planned for spring 2012 with the first report on model improvement over time to be presented at 2012 2ummer workshop.

2) Plasma parameters at the geosynchronous orbit.

To proceed with the study SOPA ion corrections for MPA are needed for pressure comparison. A group of LANL scientists are working on removal of electron contamination from the low- energy ion channels of SOPA. We exxpected completion of the first round of model-data comparison before the end of 2012.

3) Magnetopause crossings by geosynchronous satellite.

Preliminary analysis of Challenge results demonstrated significant differences between observations and model predictions. The unexpected result is that magnetopause standoff distance varies significantly for different global MHD codes. To address the issue in more details we initiated baseline model comparison study, when researchers run different MHD codes with different settings for various solar wind and IMF conditions and compare the results.
Preliminary analysis of the results at 2010 summer workshop excluded a number of possible sources for disagreement (e.g., such as grid resolution or value of anomalous resistivity). The latest idea is that the most likely source for the discrepancies are differences in inner boundary conditions. The decision was made to continue the study with the goal to resolve the issue within the next two years. We plan to initiate collaborations on this topic with FGs in magnetopause research area and with FG magnetic reconnection.

4) Dst index.

The Dst index Challenge originated in summer 2009 is a joint project with Inner Magnetisphere Focus group (liaison Dan Welling). The preliminary results were discussed at 2010 summer workshop. Report on the first round of study will be presented at the fall 2010 mini-workshop. Different ways of Dst index calculations are currently being analyzed. We plan to finalize the paper to be submitted to the Space Weather Journal before the summer workshop 2011.

5) Heat flux into ionosphere.

Heat flux into ionosphere metrics study was initiated in summer 2010. This is a joint project with Dayside FAC and Energy Deposition focus group (liaison Stefan Eriksson). The study involves comparison with Poynting flux time series derived from DMSP observations. To facilitate the research two additional events were added to the original four GEM events. This study is of potential interest to CEDAR community (as was agreed at the CEDAR 2010 summer workshop). Simulations, data preparation, and tool development for model output postrocessing are currently on the way. We plan to present the first results for the discussion at summer workshop 2011. We expect this project to continue until the end of 2012 and beyond.

6) Auroral oval position.

In summer 2010 we agreed on the importance to include auroral oval position metrics study. This metrics study is of primary interest to a number of GGCM model operational users including US Air Force. This study is also of a potential interest to the CEDAR community. The discussion on the details of this challenge is planned for the fall 2010 mini Workshop. We plan to continue this study beyond 2012.

'''Joint GEM-CEDAR Challenge'''

To analyze the effects geospace environment on the ionosphere we are planning to involve CEDAR Community to the Modeling Challenge. This activity is especially relevant due to upcoming joint GEM-CEDAR Workshop in 2011. Preliminary discussion with ionosphere modelers at CEDAR was held at CEDAR 2009 and 2010 Workshops. GEM M&V FG co-chairs were involved in the organizing of the CEDAR Electrodynamics-Thermosphere-Ionosphere Challenge. CEDAR modelers included GEM challenge events for the series of planned comparative studies. Further, many of the magnetospheric models are coupled to ionosphere-thermosphere models, therefore, the metrics can be conducted for both coupled and uncoupled simulations on both models.

'''Baseline model comparison'''

An aspect of validating models is to determine how well they solve the equation set that they are supposed to be solving. This type of validation has to do with checking the numerics of the codes. The method in which this validation will be conducted is to have researchers run different MHD codes for various solar wind and IMF conditions and compare the results. For this, we have requested that modelers run a time period in which the solar wind stays constant at 5/cc and -400 km/s, while the IMF Bz drops every few hours from -5, -10, -20, -30, -35, to -40 nT. The ionospheric conductance was held constant at 5 mhos. Another series of runs will change the solar wind ram pressure, while keeping the IMF Bz equal to – 10 nt. Initial simulation results were presented at 2009 and 2010 summer workshops. It was shown that many of the models had significant differences. It was decided upon that the subsolar magnetopause location, the cusp location, and the current structures at the magnetopause will be investigated under the different IMF conditions. Further investigations will include (1) examining the reconnection rate in the different codes to determine how each handles reconnection for the different IMF orientations; (2) examining the tail length, the amount of open flux in the polar caps and the plasma sheet density during the different intervals;
(3) the cross polar cap potential; and (4) the Dst as a function of time. With these types of comparisons, the GGCM Metrics and Validation Focus Group can collaborate with other focus groups within the GEM community. It is expected that the FG will arrange a special issue of a journal to capture the results of these comparisons.

'''Metrics and Validation Focus Group'''
'''Status Report'''

''Current Co-Chairs (2005-2012): Masha Kuznetsova (CCMC), Aaron Ridley (Univ. of Michigan).
New Co-Chairs (2012-2015); Tim Guild (Aerospace Corp), Lutz Rastaetter (CCMC), Howard Singer (NOAA)''

In summer 2008 the GGCM Metrics and Validation Focus Group initiated the GGCM modeling Challenge. The goals of the Challenge:

• Evaluate the current state of the space science models and track model improvements over time

• Facilitate interaction between research and operation communities

• Facilitate collaboration among modelers and data providers and research communities.

• Facilitate further model improvement.

The project focuses on various scientific and operational aspects of GGCM model performance and addresses challenges of model-data comparisons and metrics studies (e.g., model output and observational time series preparation for comparison, measurement uncertainty, metrics selection).

The following model/data comparisons (Matrics Studies) are involved in the Modeling Challenge:

Metric Study 1: Magnetic field at geosynchronous orbit (GOES)

Metric Study 2: Magnetopause crossings by geosynchronous satellite (GOES and LANL)

Metric Study 3: Plasma density/temperature at geosynchronous orbit (LANL)

Metric Study 4: Ground magnetic perturbations (ground based magnetometers)

Metric Study 5: Dst index (added at 2009 summer workshop)

Metric Study 6: Heat flux into ionosphere (added at 2010 summer workshop)

Metrics Study 7: Auroral oval position (study of interest to US Airforce, details to be discussed at fall 2010 mini-workshop)

Four events were selected at the GEM 2008 Workshop:

Event 1: Oct 29, 2003 06:00 UT - Oct 30, 06:00 UT (Kp = 9, Dst_min=-353nT)

Event 2: Dec 14, 2006 12:00 UT - Dec 16, 00:00 UT (Kp = 8, Dst_min=-139nT)

Event 3: Aug 31, 2001 00:00 UT - Sep 01, 00:00 UT (Kp = 4, Dst_min=-40nT)

Event 4: Aug 31, 2005 10:00 UT - Sep 01, 12:00 UT (Kp = 7, Dst_min=-131nT)

Two more events were added in summer 2010 for metrics study 6 on request of Dayside FAC and Energy Deposition focus group:

Event 5: May 15, 2005 00:00 UT - May 16, 2005, 00:00 UT

Event 6: July 9, 2005 00:00 UT - July 12, 2005, 00:00 UT

'''[http://gem.epss.ucla.edu/mediawiki/pdf/status.pdf Status of on-going metrics studies and future plans:]'''

1) Ground magnetic perturbations and magnetic field at geosynchronous orbit.
The first results of metrics studies 1 and 4 discussed at GEM 2009 and 2010 summer workshops are available at the CCMC website and at the GEM wiki. Two papers (with all Challenge participants as co-authors) are submitted to the Space Weather Journal.
Pulkkinen, A., M. Kuznetsova, A. Ridley, J. Raeder, A. Vapirev, D. Weimer, R. Weigel, M. Wiltberger, G. Millward8, L. Rastaetter, M.Hesse, H. J. Singer and A. Chulaki, GEM 2008-2009 Challenge: ground magnetic field perturbations, submitted to Space Weather Journal, 2009
Rastatter, L., M. M. Kuznetsova, A. Vapirev, A. Ridley, V. G. Merkin,
A. Pulkkinen M. Hesse, H. J. Singer, GEM 2008-2009 Challenge: magnetic fjelds at geosynchronous satellite positions, submitted to Space Weather Journal, 2010.
The principal conclusion of these studies is that ranking of the models is strongly dependent on the type of metric (the way how observational and modeled time series are compared) used to evaluate the model performance. Type of metrics to be used depends on the application and should be defined by model science and operational users. Metrics 4 is suggested for the Operational Metrics by NOAA SWPC. On NOAA SWPC request metrics format will be modified to focus on regional Kp and dB/dt. CCMC is working with the community to develop an automated system that will allow repeating the exercise on regular basis. We will continue dialog with the operations community to refine the metrics format. The second round of model-data comparison is planned for spring 2012 with the first report on model improvement over time to be presented at 2012 2ummer workshop.

2) Plasma parameters at the geosynchronous orbit.

To proceed with the study SOPA ion corrections for MPA are needed for pressure comparison. A group of LANL scientists are working on removal of electron contamination from the low- energy ion channels of SOPA. We exxpected completion of the first round of model-data comparison before the end of 2012.

3) Magnetopause crossings by geosynchronous satellite.

Preliminary analysis of Challenge results demonstrated significant differences between observations and model predictions. The unexpected result is that magnetopause standoff distance varies significantly for different global MHD codes. To address the issue in more details we initiated baseline model comparison study, when researchers run different MHD codes with different settings for various solar wind and IMF conditions and compare the results.
Preliminary analysis of the results at 2010 summer workshop excluded a number of possible sources for disagreement (e.g., such as grid resolution or value of anomalous resistivity). The latest idea is that the most likely source for the discrepancies are differences in inner boundary conditions. The decision was made to continue the study with the goal to resolve the issue within the next two years. We plan to initiate collaborations on this topic with FGs in magnetopause research area and with FG magnetic reconnection.

4) Dst index.

The Dst index Challenge originated in summer 2009 is a joint project with Inner Magnetisphere Focus group (liaison Dan Welling). The preliminary results were discussed at 2010 summer workshop. Report on the first round of study will be presented at the fall 2010 mini-workshop. Different ways of Dst index calculations are currently being analyzed. We plan to finalize the paper to be submitted to the Space Weather Journal before the summer workshop 2011.

5) Heat flux into ionosphere.

Heat flux into ionosphere metrics study was initiated in summer 2010. This is a joint project with Dayside FAC and Energy Deposition focus group (liaison Stefan Eriksson). The study involves comparison with Poynting flux time series derived from DMSP observations. To facilitate the research two additional events were added to the original four GEM events. This study is of potential interest to CEDAR community (as was agreed at the CEDAR 2010 summer workshop). Simulations, data preparation, and tool development for model output postrocessing are currently on the way. We plan to present the first results for the discussion at summer workshop 2011. We expect this project to continue until the end of 2012 and beyond.

6) Auroral oval position.

In summer 2010 we agreed on the importance to include auroral oval position metrics study. This metrics study is of primary interest to a number of GGCM model operational users including US Air Force. This study is also of a potential interest to the CEDAR community. The discussion on the details of this challenge is planned for the fall 2010 mini Workshop. We plan to continue this study beyond 2012.

'''Joint GEM-CEDAR Challenge'''

To analyze the effects geospace environment on the ionosphere we are planning to involve CEDAR Community to the Modeling Challenge. This activity is especially relevant due to upcoming joint GEM-CEDAR Workshop in 2011. Preliminary discussion with ionosphere modelers at CEDAR was held at CEDAR 2009 and 2010 Workshops. GEM M&V FG co-chairs were involved in the organizing of the CEDAR Electrodynamics-Thermosphere-Ionosphere Challenge. CEDAR modelers included GEM challenge events for the series of planned comparative studies. Further, many of the magnetospheric models are coupled to ionosphere-thermosphere models, therefore, the metrics can be conducted for both coupled and uncoupled simulations on both models.

'''Baseline model comparison'''

An aspect of validating models is to determine how well they solve the equation set that they are supposed to be solving. This type of validation has to do with checking the numerics of the codes. The method in which this validation will be conducted is to have researchers run different MHD codes for various solar wind and IMF conditions and compare the results. For this, we have requested that modelers run a time period in which the solar wind stays constant at 5/cc and -400 km/s, while the IMF Bz drops every few hours from -5, -10, -20, -30, -35, to -40 nT. The ionospheric conductance was held constant at 5 mhos. Another series of runs will change the solar wind ram pressure, while keeping the IMF Bz equal to – 10 nt. Initial simulation results were presented at 2009 and 2010 summer workshops. It was shown that many of the models had significant differences. It was decided upon that the subsolar magnetopause location, the cusp location, and the current structures at the magnetopause will be investigated under the different IMF conditions. Further investigations will include (1) examining the reconnection rate in the different codes to determine how each handles reconnection for the different IMF orientations; (2) examining the tail length, the amount of open flux in the polar caps and the plasma sheet density during the different intervals;
(3) the cross polar cap potential; and (4) the Dst as a function of time. With these types of comparisons, the GGCM Metrics and Validation Focus Group can collaborate with other focus groups within the GEM community. It is expected that the FG will arrange a special issue of a journal to capture the results of these comparisons.

'''Metrics and Validation Focus Group'''
'''Status Report'''

''Current Co-Chairs (2005-2012): Masha Kuznetsova (CCMC), Aaron Ridley (Univ. of Michigan).
New Co-Chairs (2012-2015); Tim Guild (Aerospace Corp), Lutz Rastaetter (CCMC), Howard Singer (NOAA)''

In summer 2008 the GGCM Metrics and Validation Focus Group initiated the GGCM modeling Challenge. The goals of the Challenge:

• Evaluate the current state of the space science models and track model improvements over time

• Facilitate interaction between research and operation communities

• Facilitate collaboration among modelers and data providers and research communities.

• Facilitate further model improvement.

The project focuses on various scientific and operational aspects of GGCM model performance and addresses challenges of model-data comparisons and metrics studies (e.g., model output and observational time series preparation for comparison, measurement uncertainty, metrics selection).

The following model/data comparisons (Matrics Studies) are involved in the Modeling Challenge:

Metric Study 1: Magnetic field at geosynchronous orbit (GOES)

Metric Study 2: Magnetopause crossings by geosynchronous satellite (GOES and LANL)

Metric Study 3: Plasma density/temperature at geosynchronous orbit (LANL)

Metric Study 4: Ground magnetic perturbations (ground based magnetometers)

Metric Study 5: Dst index (added at 2009 summer workshop)

Metric Study 6: Heat flux into ionosphere (added at 2010 summer workshop)

Metrics Study 7: Auroral oval position (study of interest to US Airforce, details to be discussed at fall 2010 mini-workshop)

Four events were selected at the GEM 2008 Workshop:

Event 1: Oct 29, 2003 06:00 UT - Oct 30, 06:00 UT (Kp = 9, Dst_min=-353nT)

Event 2: Dec 14, 2006 12:00 UT - Dec 16, 00:00 UT (Kp = 8, Dst_min=-139nT)

Event 3: Aug 31, 2001 00:00 UT - Sep 01, 00:00 UT (Kp = 4, Dst_min=-40nT)

Event 4: Aug 31, 2005 10:00 UT - Sep 01, 12:00 UT (Kp = 7, Dst_min=-131nT)

Two more events were added in summer 2010 for metrics study 6 on request of Dayside FAC and Energy Deposition focus group:

Event 5: May 15, 2005 00:00 UT - May 16, 2005, 00:00 UT

Event 6: July 9, 2005 00:00 UT - July 12, 2005, 00:00 UT

'''[http://gem.epss.ucla.edu/mediawiki/pdf/status.pdf Status of on-going metrics studies and future plans:]'''

1) Ground magnetic perturbations and magnetic field at geosynchronous orbit.
The first results of metrics studies 1 and 4 discussed at GEM 2009 and 2010 summer workshops are available at the CCMC website and at the GEM wiki. Two papers (with all Challenge participants as co-authors) are submitted to the Space Weather Journal.
Pulkkinen, A., M. Kuznetsova, A. Ridley, J. Raeder, A. Vapirev, D. Weimer, R. Weigel, M. Wiltberger, G. Millward8, L. Rastaetter, M.Hesse, H. J. Singer and A. Chulaki, GEM 2008-2009 Challenge: ground magnetic field perturbations, submitted to Space Weather Journal, 2009
Rastatter, L., M. M. Kuznetsova, A. Vapirev, A. Ridley, V. G. Merkin,
A. Pulkkinen M. Hesse, H. J. Singer, GEM 2008-2009 Challenge: magnetic fjelds at geosynchronous satellite positions, submitted to Space Weather Journal, 2010.
The principal conclusion of these studies is that ranking of the models is strongly dependent on the type of metric (the way how observational and modeled time series are compared) used to evaluate the model performance. Type of metrics to be used depends on the application and should be defined by model science and operational users. Metrics 4 is suggested for the Operational Metrics by NOAA SWPC. On NOAA SWPC request metrics format will be modified to focus on regional Kp and dB/dt. CCMC is working with the community to develop an automated system that will allow repeating the exercise on regular basis. We will continue dialog with the operations community to refine the metrics format. The second round of model-data comparison is planned for spring 2012 with the first report on model improvement over time to be presented at 2012 2ummer workshop.

2) Plasma parameters at the geosynchronous orbit.

To proceed with the study SOPA ion corrections for MPA are needed for pressure comparison. A group of LANL scientists are working on removal of electron contamination from the low- energy ion channels of SOPA. We exxpected completion of the first round of model-data comparison before the end of 2012.

3) Magnetopause crossings by geosynchronous satellite.

Preliminary analysis of Challenge results demonstrated significant differences between observations and model predictions. The unexpected result is that magnetopause standoff distance varies significantly for different global MHD codes. To address the issue in more details we initiated baseline model comparison study, when researchers run different MHD codes with different settings for various solar wind and IMF conditions and compare the results.
Preliminary analysis of the results at 2010 summer workshop excluded a number of possible sources for disagreement (e.g., such as grid resolution or value of anomalous resistivity). The latest idea is that the most likely source for the discrepancies are differences in inner boundary conditions. The decision was made to continue the study with the goal to resolve the issue within the next two years. We plan to initiate collaborations on this topic with FGs in magnetopause research area and with FG magnetic reconnection.

4) Dst index.

The Dst index Challenge originated in summer 2009 is a joint project with Inner Magnetisphere Focus group (liaison Dan Welling). The preliminary results were discussed at 2010 summer workshop. Report on the first round of study will be presented at the fall 2010 mini-workshop. Different ways of Dst index calculations are currently being analyzed. We plan to finalize the paper to be submitted to the Space Weather Journal before the summer workshop 2011.

5) Heat flux into ionosphere.

Heat flux into ionosphere metrics study was initiated in summer 2010. This is a joint project with Dayside FAC and Energy Deposition focus group (liaison Stefan Eriksson). The study involves comparison with Poynting flux time series derived from DMSP observations. To facilitate the research two additional events were added to the original four GEM events. This study is of potential interest to CEDAR community (as was agreed at the CEDAR 2010 summer workshop). Simulations, data preparation, and tool development for model output postrocessing are currently on the way. We plan to present the first results for the discussion at summer workshop 2011. We expect this project to continue until the end of 2012 and beyond.

6) Auroral oval position.

In summer 2010 we agreed on the importance to include auroral oval position metrics study. This metrics study is of primary interest to a number of GGCM model operational users including US Air Force. This study is also of a potential interest to the CEDAR community. The discussion on the details of this challenge is planned for the fall 2010 mini Workshop. We plan to continue this study beyond 2012.

'''Joint GEM-CEDAR Challenge'''

To analyze the effects geospace environment on the ionosphere we are planning to involve CEDAR Community to the Modeling Challenge. This activity is especially relevant due to upcoming joint GEM-CEDAR Workshop in 2011. Preliminary discussion with ionosphere modelers at CEDAR was held at CEDAR 2009 and 2010 Workshops. GEM M&V FG co-chairs were involved in the organizing of the CEDAR Electrodynamics-Thermosphere-Ionosphere Challenge. CEDAR modelers included GEM challenge events for the series of planned comparative studies. Further, many of the magnetospheric models are coupled to ionosphere-thermosphere models, therefore, the metrics can be conducted for both coupled and uncoupled simulations on both models.

'''Baseline model comparison'''

An aspect of validating models is to determine how well they solve the equation set that they are supposed to be solving. This type of validation has to do with checking the numerics of the codes. The method in which this validation will be conducted is to have researchers run different MHD codes for various solar wind and IMF conditions and compare the results. For this, we have requested that modelers run a time period in which the solar wind stays constant at 5/cc and -400 km/s, while the IMF Bz drops every few hours from -5, -10, -20, -30, -35, to -40 nT. The ionospheric conductance was held constant at 5 mhos. Another series of runs will change the solar wind ram pressure, while keeping the IMF Bz equal to – 10 nt. Initial simulation results were presented at 2009 and 2010 summer workshops. It was shown that many of the models had significant differences. It was decided upon that the subsolar magnetopause location, the cusp location, and the current structures at the magnetopause will be investigated under the different IMF conditions. Further investigations will include (1) examining the reconnection rate in the different codes to determine how each handles reconnection for the different IMF orientations; (2) examining the tail length, the amount of open flux in the polar caps and the plasma sheet density during the different intervals;
(3) the cross polar cap potential; and (4) the Dst as a function of time. With these types of comparisons, the GGCM Metrics and Validation Focus Group can collaborate with other focus groups within the GEM community. It is expected that the FG will arrange a special issue of a journal to capture the results of these comparisons.

'''[http://gem.epss.ucla.edu/mediawiki/pdf/status.pdf Status of on-going metrics studies and future plans:]'''

1) Ground magnetic perturbations and magnetic field at geosynchronous orbit.
The first results of metrics studies 1 and 4 discussed at GEM 2009 and 2010 summer workshops are available at the CCMC website and at the GEM wiki. Two papers (with all Challenge participants as co-authors) are submitted to the Space Weather Journal.
Pulkkinen, A., M. Kuznetsova, A. Ridley, J. Raeder, A. Vapirev, D. Weimer, R. Weigel, M. Wiltberger, G. Millward8, L. Rastaetter, M.Hesse, H. J. Singer and A. Chulaki, GEM 2008-2009 Challenge: ground magnetic field perturbations, submitted to Space Weather Journal, 2009
Rastatter, L., M. M. Kuznetsova, A. Vapirev, A. Ridley, V. G. Merkin,
A. Pulkkinen M. Hesse, H. J. Singer, GEM 2008-2009 Challenge: magnetic fjelds at geosynchronous satellite positions, submitted to Space Weather Journal, 2010.
The principal conclusion of these studies is that ranking of the models is strongly dependent on the type of metric (the way how observational and modeled time series are compared) used to evaluate the model performance. Type of metrics to be used depends on the application and should be defined by model science and operational users. Metrics 4 is suggested for the Operational Metrics by NOAA SWPC. On NOAA SWPC request metrics format will be modified to focus on regional Kp and dB/dt. CCMC is working with the community to develop an automated system that will allow repeating the exercise on regular basis. We will continue dialog with the operations community to refine the metrics format. The second round of model-data comparison is planned for spring 2012 with the first report on model improvement over time to be presented at 2012 2ummer workshop.

2) Plasma parameters at the geosynchronous orbit.

To proceed with the study SOPA ion corrections for MPA are needed for pressure comparison. A group of LANL scientists are working on removal of electron contamination from the low- energy ion channels of SOPA. We exxpected completion of the first round of model-data comparison before the end of 2012.

3) Magnetopause crossings by geosynchronous satellite.

Preliminary analysis of Challenge results demonstrated significant differences between observations and model predictions. The unexpected result is that magnetopause standoff distance varies significantly for different global MHD codes. To address the issue in more details we initiated baseline model comparison study, when researchers run different MHD codes with different settings for various solar wind and IMF conditions and compare the results.
Preliminary analysis of the results at 2010 summer workshop excluded a number of possible sources for disagreement (e.g., such as grid resolution or value of anomalous resistivity). The latest idea is that the most likely source for the discrepancies are differences in inner boundary conditions. The decision was made to continue the study with the goal to resolve the issue within the next two years. We plan to initiate collaborations on this topic with FGs in magnetopause research area and with FG magnetic reconnection.

4) Dst index.

The Dst index Challenge originated in summer 2009 is a joint project with Inner Magnetisphere Focus group (liaison Dan Welling). The preliminary results were discussed at 2010 summer workshop. Report on the first round of study will be presented at the fall 2010 mini-workshop. Different ways of Dst index calculations are currently being analyzed. We plan to finalize the paper to be submitted to the Space Weather Journal before the summer workshop 2011.

5) Heat flux into ionosphere.

Heat flux into ionosphere metrics study was initiated in summer 2010. This is a joint project with Dayside FAC and Energy Deposition focus group (liaison Stefan Eriksson). The study involves comparison with Poynting flux time series derived from DMSP observations. To facilitate the research two additional events were added to the original four GEM events. This study is of potential interest to CEDAR community (as was agreed at the CEDAR 2010 summer workshop). Simulations, data preparation, and tool development for model output postrocessing are currently on the way. We plan to present the first results for the discussion at summer workshop 2011. We expect this project to continue until the end of 2012 and beyond.

6) Auroral oval position.

In summer 2010 we agreed on the importance to include auroral oval position metrics study. This metrics study is of primary interest to a number of GGCM model operational users including US Air Force. This study is also of a potential interest to the CEDAR community. The discussion on the details of this challenge is planned for the fall 2010 mini Workshop. We plan to continue this study beyond 2012.

'''Joint GEM-CEDAR Challenge'''

To analyze the effects geospace environment on the ionosphere we are planning to involve CEDAR Community to the Modeling Challenge. This activity is especially relevant due to upcoming joint GEM-CEDAR Workshop in 2011. Preliminary discussion with ionosphere modelers at CEDAR was held at CEDAR 2009 and 2010 Workshops. GEM M&V FG co-chairs were involved in the organizing of the CEDAR Electrodynamics-Thermosphere-Ionosphere Challenge. CEDAR modelers included GEM challenge events for the series of planned comparative studies. Further, many of the magnetospheric models are coupled to ionosphere-thermosphere models, therefore, the metrics can be conducted for both coupled and uncoupled simulations on both models.

'''Baseline model comparison'''

An aspect of validating models is to determine how well they solve the equation set that they are supposed to be solving. This type of validation has to do with checking the numerics of the codes. The method in which this validation will be conducted is to have researchers run different MHD codes for various solar wind and IMF conditions and compare the results. For this, we have requested that modelers run a time period in which the solar wind stays constant at 5/cc and -400 km/s, while the IMF Bz drops every few hours from -5, -10, -20, -30, -35, to -40 nT. The ionospheric conductance was held constant at 5 mhos. Another series of runs will change the solar wind ram pressure, while keeping the IMF Bz equal to – 10 nt. Initial simulation results were presented at 2009 and 2010 summer workshops. It was shown that many of the models had significant differences. It was decided upon that the subsolar magnetopause location, the cusp location, and the current structures at the magnetopause will be investigated under the different IMF conditions. Further investigations will include (1) examining the reconnection rate in the different codes to determine how each handles reconnection for the different IMF orientations; (2) examining the tail length, the amount of open flux in the polar caps and the plasma sheet density during the different intervals;
(3) the cross polar cap potential; and (4) the Dst as a function of time. With these types of comparisons, the GGCM Metrics and Validation Focus Group can collaborate with other focus groups within the GEM community. It is expected that the FG will arrange a special issue of a journal to capture the results of these comparisons.

'''Model Uncertainty: Dealing with uncertain physical processes and boundary conditions'''

In this session we solicit contributions discussing how model uncertainties and uncertain boundary conditions affect model results and validation. Specifically solicited are strategies to accommodate uncertainty in modeled physical processes (e.g. uncertain radiation belt diffusion coefficients), uncertainty in boundary conditions (e.g. upstream solar wind), or the validation of models at their boundaries (such as ground-based magnetometers).

We will introduce a challenge based on previously run magnetopause standoff simulations that compared model results to magnetopause crossings of geo-synchronous satellites. The few crossings observed during strong events revealed significant discrepancies between the major magnetospheric MHD models. We plan to revisit the challenge on the basis of selected events with steady and changing solar wind conditions and observations near the nose of the magnetosphere. The role of boundary conditions applied at the inner boundary (e.g., ionospheric conductance and convection, plasma density and temperature, magnetic field) can be tested. Some of the questions that can be addressed are:

* Which model is better suited to predict magnetopause position near the nose of the magnetosphere under typical conditions/storm time conditions?
* What model assumptions affect the model predictions significantly and lead to differences between models?
* How does the magnetopause change during extreme events
* How sensitive is model performance to changes of the boundary conditions?
* Can we define common settings for the inner boundary location, and the plasma density or temperature applied at this boundary?

We also anticipate presentations on topics such as the influence of the plasma sheet boundary conditions on ring current development and also welcome specifications of uncertainties derived from observations and lessons from data assimilation and ensemble modeling methods.

Validating Models Under Extreme Geomagnetic Conditions.

Extreme events in the geospace environment are among the most interesting scientifically as well as important for their space weather consequences. The goals for this session are: to show model results for extreme events in the magnetosphere, to share information about the range of conditions where models have been validated, to assess methods for validating model performance with limited observations (such as for early historical events), and to assess the reliability of a model outside the range in which it has been validated. These results will guide our understanding of the magnetosphere under extreme conditions, and provide insight into what physics needs to be incorporated into models so that they perform better during extreme events. Contributions to these and related issues are welcome.

'''Model Uncertainty: Dealing with uncertain physical processes and boundary conditions'''

In this session we solicit contributions discussing how model uncertainties and uncertain boundary conditions affect model results and validation. Specifically solicited are strategies to accommodate uncertainty in modeled physical processes (e.g. uncertain radiation belt diffusion coefficients), uncertainty in boundary conditions (e.g. upstream solar wind), or the validation of models at their boundaries (such as ground-based magnetometers).

We will introduce a challenge based on previously run magnetopause standoff simulations that compared model results to magnetopause crossings of geo-synchronous satellites. The few crossings observed during strong events revealed significant discrepancies between the major magnetospheric MHD models. We plan to revisit the challenge on the basis of selected events with steady and changing solar wind conditions and observations near the nose of the magnetosphere. The role of boundary conditions applied at the inner boundary (e.g., ionospheric conductance and convection, plasma density and temperature, magnetic field) can be tested. Some of the questions that can be addressed are:

* Which model is better suited to predict magnetopause position near the nose of the magnetosphere under typical conditions/storm time conditions?
* What model assumptions affect the model predictions significantly and lead to differences between models?
* How does the magnetopause change during extreme events
* How sensitive is model performance to changes of the boundary conditions?
* Can we define common settings for the inner boundary location, and the plasma density or temperature applied at this boundary?

We also anticipate presentations on topics such as the influence of the plasma sheet boundary conditions on ring current development and also welcome specifications of uncertainties derived from observations and lessons from data assimilation and ensemble modeling methods.

Validating Models Under Extreme Geomagnetic Conditions.

Extreme events in the geospace environment are among the most interesting scientifically as well as important for their space weather consequences. The goals for this session are: to show model results for extreme events in the magnetosphere, to share information about the range of conditions where models have been validated, to assess methods for validating model performance with limited observations (such as for early historical events), and to assess the reliability of a model outside the range in which it has been validated. These results will guide our understanding of the magnetosphere under extreme conditions, and provide insight into what physics needs to be incorporated into models so that they perform better during extreme events. Contributions to these and related issues are welcome.

==== [Special] Strategic Priorities for Funding in the NSF Antarctic Program (Ports Ballroom IV-V) ====

NSF has requested that the National Academy of Science develop a consensus recommendation on the most compelling research that can be supported in the coming decade and outline steps forward to implement this research. This meeting is to engage the space science community to participate in the development of this consensus recommendation. The Antarctic can be a platform for measurements and investigation of space weather phenomena and several measurement programs are presently active. How should funding priorities be set for this research during the coming decade? Please help to establish these priorities. Very broad key scientific questions have been identified in the 2011 NRC report “Future Science Opportunities in the Antarctic and Southern Ocean”. The relevant question for our community is “What can the Antarctic platform reveal about the interactions between the Earth and the space environment”. The results from the NAS committee established to develop funding priorities will have an important impact on funding decisions at NSF and our research community needs to be strongly represented.

'''Model Uncertainty: Dealing with uncertain physical processes and boundary conditions'''

In this session we solicit contributions discussing how model uncertainties and uncertain boundary conditions affect model results and validation. Specifically solicited are strategies to accommodate uncertainty in modeled physical processes (e.g. uncertain radiation belt diffusion coefficients), uncertainty in boundary conditions (e.g. upstream solar wind), or the validation of models at their boundaries (such as ground-based magnetometers).

We will introduce a challenge based on previously run magnetopause standoff simulations that compared model results to magnetopause crossings of geo-synchronous satellites. The few crossings observed during strong events revealed significant discrepancies between the major magnetospheric MHD models. We plan to revisit the challenge on the basis of selected events with steady and changing solar wind conditions and observations near the nose of the magnetosphere. The role of boundary conditions applied at the inner boundary (e.g., ionospheric conductance and convection, plasma density and temperature, magnetic field) can be tested. Some of the questions that can be addressed are:

* Which model is better suited to predict magnetopause position near the nose of the magnetosphere under typical conditions/storm time conditions?
* What model assumptions affect the model predictions significantly and lead to differences between models?
* How does the magnetopause change during extreme events
* How sensitive is model performance to changes of the boundary conditions?
* Can we define common settings for the inner boundary location, and the plasma density or temperature applied at this boundary?

We also anticipate presentations on topics such as the influence of the plasma sheet boundary conditions on ring current development and also welcome specifications of uncertainties derived from observations and lessons from data assimilation and ensemble modeling methods.

Validating Models Under Extreme Geomagnetic Conditions.

Extreme events in the geospace environment are among the most interesting scientifically as well as important for their space weather consequences. The goals for this session are: to show model results for extreme events in the magnetosphere, to share information about the range of conditions where models have been validated, to assess methods for validating model performance with limited observations (such as for early historical events), and to assess the reliability of a model outside the range in which it has been validated. These results will guide our understanding of the magnetosphere under extreme conditions, and provide insight into what physics needs to be incorporated into models so that they perform better during extreme events. Contributions to these and related issues are welcome.

NSF has requested that the National Academy of Science develop a consensus recommendation on the most compelling research that can be supported in the coming decade and outline steps forward to implement this research. This meeting is to engage the space science community to participate in the development of this consensus recommendation. The Antarctic can be a platform for measurements and investigation of space weather phenomena and several measurement programs are presently active. How should funding priorities be set for this research during the coming decade? Please help to establish these priorities. Very broad key scientific questions have been identified in the 2011 NRC report “Future Science Opportunities in the Antarctic and Southern Ocean”. The relevant question for our community is “What can the Antarctic platform reveal about the interactions between the Earth and the space environment”. The results from the NAS committee established to develop funding priorities will have an important impact on funding decisions at NSF and our research community needs to be strongly represented.

'''Model Uncertainty: Dealing with uncertain physical processes and boundary conditions'''

In this session we solicit contributions discussing how model uncertainties and uncertain boundary conditions affect model results and validation. Specifically solicited are strategies to accommodate uncertainty in modeled physical processes (e.g. uncertain radiation belt diffusion coefficients), uncertainty in boundary conditions (e.g. upstream solar wind), or the validation of models at their boundaries (such as ground-based magnetometers).

We will introduce a challenge based on previously run magnetopause standoff simulations that compared model results to magnetopause crossings of geo-synchronous satellites. The few crossings observed during strong events revealed significant discrepancies between the major magnetospheric MHD models. We plan to revisit the challenge on the basis of selected events with steady and changing solar wind conditions and observations near the nose of the magnetosphere. The role of boundary conditions applied at the inner boundary (e.g., ionospheric conductance and convection, plasma density and temperature, magnetic field) can be tested. Some of the questions that can be addressed are:

* Which model is better suited to predict magnetopause position near the nose of the magnetosphere under typical conditions/storm time conditions?
* What model assumptions affect the model predictions significantly and lead to differences between models?
* How does the magnetopause change during extreme events
* How sensitive is model performance to changes of the boundary conditions?
* Can we define common settings for the inner boundary location, and the plasma density or temperature applied at this boundary?

We also anticipate presentations on topics such as the influence of the plasma sheet boundary conditions on ring current development and also welcome specifications of uncertainties derived from observations and lessons from data assimilation and ensemble modeling methods.

Validating Models Under Extreme Geomagnetic Conditions.

Extreme events in the geospace environment are among the most interesting scientifically as well as important for their space weather consequences. The goals for this session are: to show model results for extreme events in the magnetosphere, to share information about the range of conditions where models have been validated, to assess methods for validating model performance with limited observations (such as for early historical events), and to assess the reliability of a model outside the range in which it has been validated. These results will guide our understanding of the magnetosphere under extreme conditions, and provide insight into what physics needs to be incorporated into models so that they perform better during extreme events. Contributions to these and related issues are welcome.

'''5-minute presentation limits:'''

Due to the large number of abstracts submitted to the Radiation Belts and Waves Focus Group, we would like to remind presenters to adhere to the 3-slide, 5-minute limit as much as possible. We have a limited amount of time and would like to accommodate as many speakers as we can, so we are asking presenters to please be succinct (yet convey the main point of the science clearly).

== [[FG: The Ionospheric Source of Magnetospheric Plasma|The Ionospheric Source of Magnetospheric Plasma--Measuring, Modeling and Merging into the GEM GGCM]] ==
''Conveners: Rick Chappell <rick.chappell [at] vanderbilt.edu>, Bob Schunk and Dan Welling''

We would like to invite your participation in an area of research that is directed toward creating a unified model that incorporates the outflow of plasma from the ionosphere into the creation and dynamics of the important plasma regions of the magnetosphere.

This GEM focus group has as its goal to improve the understanding of the role of the ionospheric outflow source by (1) refining outflow modeling through comparison with measurements, (2) adjusting the outflow modeling to become a compatible input to magnetospheric Geospace Global Circulation Models (GGCM), (3) comparing magnetospheric modeling results with satellite measurements and (4) examining ways in which the dynamic magnetosphere can couple back to influence the original ionospheric outflow.

We have planned the following four sessions for the upcoming GEM Snowmass meeting and would like for you to suggest topics that you would like to present in the sessions.

'''Session 1—Observational and Modeling Mysteries—June 19, 10:30am:'''
This session will be an opportunity for both modelers and experimentalists to present areas of unanswered questions in their work concerning outflow and its effects. The goal will be to solicit discussion from the GEM Ion Outflow-MMM community regarding approaches to solving the outstanding mysteries and to initiate new collaborative research in these areas.

'''Session 2—The Magnetosphere-Ionosphere System With and Without Outflow-June 19, 1:30pm:'''
This session will compare and contrast the characteristics of periods of strong outflow with periods of weak outflow in both the observational and modeling results. A focal point of this session will be to work toward a self-consistent coupling in the merging of the ionosphere and magnetosphere models considering effects such as precipitation, currents and electric fields.

'''Session 3—General Contributions in Measurements, Modeling and Merging—June 19, 3:30pm:'''
This session will cover a variety of topics related to measuring and modeling the ionospheric outflow and its effects on the magnetosphere as well as merging the ionospheric and magnetospheric models.

'''Session 4—Planning Session—June 20, 10:30am:'''
This will be an open discussion on the status of the focus group accomplishments in order to identify areas of research that are needed and approaches that can be initiated to drive new modeling, measurements and GGCM results.

Please send your topics and suggestions to Rick Chappell at rick.chappell [at] vanderbilt.edu.

We look forward to seeing you at the GEM meeting in June.

The GGCM Metrics and Validation Focus Group solicits short
contributions to three planned sessions at the upcoming GEM meeting in
Snowmass, Colorado, on Thursday and Friday, June 20-21. The session
descriptions are below. If you have a topic to discuss, please send
us a draft title so that we can begin to put together a program;
however, in the spirit of GEM, participation and brief, last-minute
informal presentations are always welcome.

'''Session 1:''' New Validation Results and Methods
In this session we solicit short presentations focusing on all aspects
of data-model comparisons. Welcomed themes could include geospace
model validation using regional ground magnetometer indices, model
responses to dynamic magnetopause boundaries, long-term
"climatological" model validation, using multi-variate metrics to
assess model performance, or any related contribution.

'''Session 2:''' How Validation Studies Guide Model Improvements:
In this session, we solicit short presentations on specific examples
of how discrepancies between models and observations have led to a
better understanding of the physics that needs to be incorporated into
models. Studies, or ideas, on studies involving model sensitivity to
inputs and various model parameters are welcome. The session will
include a discussion on better ways to design metrics and validation
studies to uncover missing physics in models.

'''Session 3:''' Validation of MHD models Coupled with other modules such
as the Ring Current and Polar Outflow
In this session we will investigate recent advances in the development
of coupled models of the magnetosphere, inner magnetosphere, the
plasmasphere/polar wind, and the ionosphere/thermosphere. We solicit
short presentations on methods to link models, validate the outputs
and constrain coupled model systems using observations. Emphasis
should be placed on new physical processes that are described by the
coupled models and on effects that remain out of scope and that limit
the effectiveness and stability of the coupling.

Thank you for your contributions.

''Conveners: Joseph Baker, Stan Sazykin, Mike Ruohoniemi, Peter Chi, Mark Engebretson''

Dear Colleagues,

This year's GEM Summer Workshop marks the initiation of a new Focus
Group to examine "Storm-Time Inner Magnetosphere-Ionosphere Convection
(SIMIC)". The SIMIC Focus Group will bring together observations and
modeling to examine the coupled dynamics of the inner magnetosphere
and ionosphere during geomagnetic storms. Recent improvements in
modeling and ground- and space-based instrumentation allow this topic
to be examined with unprecedented spatial and temporal resolution and
coverage. Some examples of relevant parameters of interest include:
plasma distributions, magnetic topology, convection electric fields,
and current systems. More details about the SIMIC Focus Group can be
found at:

http://gem.epss.ucla.edu/mediawikiwiki/index.php/FG:_Storm-Time_Inner_Magnetosphere-Ionosphere_Convection

We invite short presentations that highlight one or more of the
following themes:

# Improvements in self-consistent physics-based simulations of the coupled inner magnetosphere-ionosphere system during geomagnetic storms.
# Instrumentation which can be used to examine storm-time magnetosphere-ionosphere coupling over large spatial scales and validate the simulations (e.g. magnetometers, radars, imaging, GPS receivers, etc.)
# Any other discussion topics relevant to articulating an appropriate scope and emphasis for this Focus Group. (Since this is the first year, we are open to any comments or suggestions about how to move forward most effectively.)

The SIMIC Focus Group will hold two sessions on Thursday afternoon and
Friday morning. We have deliberately scheduled the sessions for late
in the week to benefit those people who aim to attend both GEM and
CEDAR.

If you would like to give a SIMIC presentation, please email Joseph
Baker (jo.baker [at] vt.edu) and Stan Sazykin (sazykin [at] rice.edu) with
a working title and short description of your talk.

Here's to a great SIMIC kick-off!

'''5-minute presentation limits:'''

Due to the large number of abstracts submitted to the Radiation Belts and Waves Focus Group, we would like to remind presenters to adhere to the 3-slide, 5-minute limit as much as possible. We have a limited amount of time and would like to accommodate as many speakers as we can, so we are asking presenters to please be succinct (yet convey the main point of the science clearly).

== [[FG: The Ionospheric Source of Magnetospheric Plasma|The Ionospheric Source of Magnetospheric Plasma--Measuring, Modeling and Merging into the GEM GGCM]] ==
''Conveners: Rick Chappell <rick.chappell [at] vanderbilt.edu>, Bob Schunk and Dan Welling''

We would like to invite your participation in an area of research that is directed toward creating a unified model that incorporates the outflow of plasma from the ionosphere into the creation and dynamics of the important plasma regions of the magnetosphere.

This GEM focus group has as its goal to improve the understanding of the role of the ionospheric outflow source by (1) refining outflow modeling through comparison with measurements, (2) adjusting the outflow modeling to become a compatible input to magnetospheric Geospace Global Circulation Models (GGCM), (3) comparing magnetospheric modeling results with satellite measurements and (4) examining ways in which the dynamic magnetosphere can couple back to influence the original ionospheric outflow.

We have planned the following four sessions for the upcoming GEM Snowmass meeting and would like for you to suggest topics that you would like to present in the sessions.

'''Session 1—Observational and Modeling Mysteries—June 19, 10:30am:'''
This session will be an opportunity for both modelers and experimentalists to present areas of unanswered questions in their work concerning outflow and its effects. The goal will be to solicit discussion from the GEM Ion Outflow-MMM community regarding approaches to solving the outstanding mysteries and to initiate new collaborative research in these areas.

'''Session 2—The Magnetosphere-Ionosphere System With and Without Outflow-June 19, 1:30pm:'''
This session will compare and contrast the characteristics of periods of strong outflow with periods of weak outflow in both the observational and modeling results. A focal point of this session will be to work toward a self-consistent coupling in the merging of the ionosphere and magnetosphere models considering effects such as precipitation, currents and electric fields.

'''Session 3—General Contributions in Measurements, Modeling and Merging—June 19, 3:30pm:'''
This session will cover a variety of topics related to measuring and modeling the ionospheric outflow and its effects on the magnetosphere as well as merging the ionospheric and magnetospheric models.

'''Session 4—Planning Session—June 20, 10:30am:'''
This will be an open discussion on the status of the focus group accomplishments in order to identify areas of research that are needed and approaches that can be initiated to drive new modeling, measurements and GGCM results.

Please send your topics and suggestions to Rick Chappell at rick.chappell [at] vanderbilt.edu.

We look forward to seeing you at the GEM meeting in June.

These sessions are scheduled at 10:30 AM to 12:15 PM and 1:30 to 3:00 PM on Thursday June 20. The Focus Group has examined the solar wind and magnetospheric conditions leading to different types of geomagnetic activity. This will be the last meeting of this Focus Group as GEM moves to other topics. We will begin with a review of our past activities and suggestions for future work. We are soliciting presentations related to the following topics:

# The occurrence of substorms as function of universal time, season, and solar cycle
# The properties of steady magnetospheric convection (SMC) and its relation to solar wind and prior substorm activity
# The occurrence and properties of sawtooth events
# The occurrence statistics of poleward boundary intensifications (PBI) during substorm phases and SMC

The GGCM Metrics and Validation Focus Group solicits short
contributions to three planned sessions at the upcoming GEM meeting in
Snowmass, Colorado, on Thursday and Friday, June 20-21. The session
descriptions are below. If you have a topic to discuss, please send
us a draft title so that we can begin to put together a program;
however, in the spirit of GEM, participation and brief, last-minute
informal presentations are always welcome.

'''Session 1:''' New Validation Results and Methods
In this session we solicit short presentations focusing on all aspects
of data-model comparisons. Welcomed themes could include geospace
model validation using regional ground magnetometer indices, model
responses to dynamic magnetopause boundaries, long-term
"climatological" model validation, using multi-variate metrics to
assess model performance, or any related contribution.

'''Session 2:''' How Validation Studies Guide Model Improvements:
In this session, we solicit short presentations on specific examples
of how discrepancies between models and observations have led to a
better understanding of the physics that needs to be incorporated into
models. Studies, or ideas, on studies involving model sensitivity to
inputs and various model parameters are welcome. The session will
include a discussion on better ways to design metrics and validation
studies to uncover missing physics in models.

'''Session 3:''' Validation of MHD models Coupled with other modules such
as the Ring Current and Polar Outflow
In this session we will investigate recent advances in the development
of coupled models of the magnetosphere, inner magnetosphere, the
plasmasphere/polar wind, and the ionosphere/thermosphere. We solicit
short presentations on methods to link models, validate the outputs
and constrain coupled model systems using observations. Emphasis
should be placed on new physical processes that are described by the
coupled models and on effects that remain out of scope and that limit
the effectiveness and stability of the coupling.

Thank you for your contributions.

Dear Colleagues,

This year's GEM Summer Workshop marks the initiation of a new Focus
Group to examine "Storm-Time Inner Magnetosphere-Ionosphere Convection
(SIMIC)". The SIMIC Focus Group will bring together observations and
modeling to examine the coupled dynamics of the inner magnetosphere
and ionosphere during geomagnetic storms. Recent improvements in
modeling and ground- and space-based instrumentation allow this topic
to be examined with unprecedented spatial and temporal resolution and
coverage. Some examples of relevant parameters of interest include:
plasma distributions, magnetic topology, convection electric fields,
and current systems. More details about the SIMIC Focus Group can be
found at:

We invite short presentations that highlight one or more of the
following themes:

# Improvements in self-consistent physics-based simulations of the coupled inner magnetosphere-ionosphere system during geomagnetic storms.
# Instrumentation which can be used to examine storm-time magnetosphere-ionosphere coupling over large spatial scales and validate the simulations (e.g. magnetometers, radars, imaging, GPS receivers, etc.)
# Any other discussion topics relevant to articulating an appropriate scope and emphasis for this Focus Group. (Since this is the first year, we are open to any comments or suggestions about how to move forward most effectively.)

The SIMIC Focus Group will hold two sessions on Thursday afternoon and
Friday morning. We have deliberately scheduled the sessions for late
in the week to benefit those people who aim to attend both GEM and
CEDAR.

If you would like to give a SIMIC presentation, please email Joseph
Baker (jo.baker [at] vt.edu) and Stan Sazykin (sazykin [at] rice.edu) with
a working title and short description of your talk.

Here's to a great SIMIC kick-off!

''Conveners: Vassilis Angelopoulos <vassilis [at] ucla.edu>, Shin Ohtani <Shin.Ohtani [at] jhuapl.edu>, Kazuo Shiokawa <shiokawa [at] stelab.nagoya-u.ac.jp>, Andrei Runov <arunov [at] igpp.ucla.edu>''

We would like to invite contributions to the Substorm Expansion Onset:
The First 10 Minutes Focus Group at the upcoming GEM meeting in
Snowmass on June 16-21, 2013. The Focus Group goals and other
information are available at:

http://gem.epss.ucla.edu/mediawikiwiki/index.php/FG12._Substorm_Expansion_Onset:_The_First_10_Minutes

For this summer we plan four 1.5 hr-long sessions to discuss

* Relative timing between onset signatures in space and on the ground
* The role of magnetotail reconnection (distant and near-Earth) in substorms and substorm-related processes, such as pseudo-breakups, PBIs, streamers, and other substorm-related phenomena (joint with the RX Focus Group)
* Substorm-related processes in the tail-dipole transition region
* Substorm onset mapping (joint with the Magnetic Mapping and Techniques Focus Group).

Since it is the Substorm Expansion Onset Focus Group final year, we
plan to allocate 10 minutes of each session for the final report
discussion.

The workshop agenda is available at
http://www.cpe.vt.edu/gem/schedule.html

Each speaker will be allotted time for 5 minutes (3 slides)
presentation, in order to ensure enough time for discussion. Please
submit tentative titles of your presentation and/or address your
questions to the FG coordinators.
