== 2018 GEM Announcement ==
The Quantitative Assessment of Radiation Belt Modeling (QARBM) focus group will be ending this year and plan to have three final sessions at the upcoming GEM workshop. 

*'''Session 1 (Wed, 03:30-05:00 PM):''' "''RB enhancement''". 
:This session will focus on quantitative assessment of the relative contributions of the acceleration, transport, and loss processes to radiation belt enhancements, including both the traditional and newly discovered physics. We will start with an invited “scene-setting” talk given by Dr. Mary Hudson, followed by short and workshop-style presentations and group discussions.

*'''Session 2 (Thu, 10:30 AM-12:00 PM):''' "''RB dropout''". 
:This session will focus on quantitative assessment of the relative contributions of the acceleration, transport, and loss processes to radiation belt dropouts, including both the traditional and newly discovered physics. The format will be the same as Session 1, including an “scene-setting” talk (invited speaker TBD), short and workshop-style presentations, and group discussions.   

*'''Session 3 (Thu, 03:30-05:00 PM):''' "''Wrap-up and Future overlook''". 
:We will first summarize the results from our RB Challenges, and then continue with panel and group discussions on the remaining open questions and future directions of radiation belt studies. Our panelists include Drs. Jacob Bortnik (confirmed), Allison Jaynes (confirmed), Wen Li (confirmed), Geoff Reeves (confirmed), Drew Turner (confirmed), and Sasha Ukhorskiy (TBD). 

Since all the sessions will be organized in discussion-based workshop mode, we invite submissions of short and informal presentations to Session 1 and Session 2 (with 3-4 slides and no intro or conclusions needed). Please send your talk title and the relevant session number to Weichao Tu (wetu@mail.wvu.edu) by Mon, June 11th, 2018. To reserve sufficient time for discussions, the talks will be scheduled based on relevance and the submission time. For the summary of RB Challenges, if you have published (or have in prep or presented at conferences) on our Challenge events, please send us the info as well. We strongly encourage you to participate in our fun group discussions in all three sessions. Thanks in advance for your contributions!

== 2017 GEM Announcement ==
We would like to solicit short presentations relevant to the following four sessions, including three independent sessions and one joint session with the “Modeling Methods and Validation” FG.

*'''Session 1 (Wed, 10:30-12:15 AM):''' "''Observations of radiation belt processes''". 
:We solicit short presentations on observational studies of the dynamical processes in the radiation belts. Possible topics include the generation and dynamics of various magnetospheric waves, wave-particle interactions in the radiation belts, and the dynamics of radiation belt particles. This session mainly focuses on observational studies and results.

*'''Session 2 (Wed, 01:30-03:00 PM):''' "''Modeling of local processes and transport''". 
:We solicit short presentations focusing on modeling the local wave-particle interactions and transport processes in the radiation belts. This first modeling session focuses on waves and structures that can have local interactions with radiation belt particles (e.g., chorus, hiss, EMIC, magnetosonic waves, nonlinear structures, etc.), and their effects on radiation belt particles. Presentations on the modeling of radiation belt transport driven by ULF waves are also invited.   

*'''Session 3 (Wed, 03:30-05:00 PM):''' "''Global modeling, metrics and validation''". 
:This is the joint session with “Modeling Methods and Validation” FG, since the two FGs have common interest in the global modeling of radiation belt (RB) dynamics and the metrics and validation methods that can be used to quantitatively assess the modeling. We call for short presentations that perform global modeling of the acceleration, transport, and loss of RB particles, test current metrics and validation for RB modeling, and/or develop new validation methods.

*'''Session 4 (Thu, 10:30-12:15 PM):''' "''New challenge results and plans''". 
:This session will focus on the following four "challenge" events:
# Stormtime Enhancement: 2013-03-17/00 UT to 2013-03-19/00 UT
# Stormtime Dropout: 2013-05-31/00 UT to 2013-06-03/00 UT
# Non-storm Enhancement: 2013-09-19/00 UT to 2013-09-21/00 UT
# Non-storm Dropout: 2013-09-23/00 UT to 2013-09-26/00 UT
:We encourage presentations on the new RB modeling results of these events as well as quantitative assessment of the established modeling results from previous meetings. More information on these events and the available resources can be found at our GEM wiki page. At last, we will wrap up and plan for future FG activities. 

If you would like to present in any of these sessions, please send your talk title and the relevant session number to Weichao Tu (wetu@mail.wvu.edu) by June 11th, 2017. Our FG activities and announcements will be updated in the GEM wiki page. Thank you very much in advance for your contributions!

== 2014 GEM Announcement ==
At this year's GEM Summer Workshop we will start a new Focus Group on "Quantitative Assessment of Radiation Belt Modeling". The goals of our FG are to bring together the current state-of-art models for the acceleration, transport, and loss processes in radiation belts, develop event-specific and global wave, plasma, and magnetic field models to drive these radiation belt models, and combine all these components to achieve a quantitative assessment of radiation belt modeling by validating against contemporary radiation belt measurements.

Five sessions have been planned for the upcoming GEM workshop: 

*'''Session 1 (Tue, 10:30-12:15 PM):''' "''Joint Session with Radiation Belts & Wave Modeling focus group''". 
:In this joint session, the RBWM FG (finishing this year) will wrap up their accomplishments in the past 5 years and then set up the stage for our introduction of the new FG of Quantitative Assessment of Radiation Belt Modeling. We will discuss the remaining open questions in RB modeling and connect them to our FG goals and challenges.

*'''Session 2 (Tue, 01:30-03:00 PM):''' "''Review existing RB models and discuss where we are and what are needed''". 
:In this session, we solicit short presentations discussing the existing models for the acceleration, transport, and loss of radiation belt particles. In general, we welcome talks that not only showcase their results, but also include discussions like: "Mechanism ____ is evidently necessary, though not sufficient since ___." We will discuss questions such as: what are "standard" RB codes not doing well enough? vs. What are we not doing at all but probably should be?   

*'''Session 3 (Tue, 03:30-05:00 PM):''' "''Various magnetospheric wave characteristics and their global distribution required in RB modeling''". 
:In this session, we solicit short presentations focusing on characterizing various wave properties that are required as inputs to RB models. The topics will cover ULF waves, chorus and hiss, EMIC waves, magnetosonic waves, etc., and their effects on RB particles. We will review the available wave models and discuss what are still missing for RB modeling.

*'''Session 4 (Wed, 10:30-12:15 PM):''' "''Seed populations, plasma density, and magnetic field configuration required in RB modeling''". 
:In this session, we solicit short presentations specifying other required inputs for driving RB simulations, which include particle seed populations, plasma density, magnetic field configuration, last closed drift shell, etc. Again, we will review what are currently available and discuss what are still missing. 

*'''Session 5 (Wed, 01:30-03:00 PM):''' "''Wrap-up discussion and plan for future FG activities''".
:In this final session, we will wrap up this year’s FG with more big-picture discussions, and plan for future FG activities for mini-GEM and next year. One important future activity is the 'RB dropout' and 'RB buildup' Challenges. Here we solicit short presentations proposing interesting dropout/buildup events for our future challenges.

If you would like to present in any of these sessions, please send your talk title and the relevant session number to Weichao Tu
(wtu@lanl.gov) by June 6, 2014. We will review the talks and announce the detailed session agenda before the meeting. Participation in discussions and brief walk-in talks are always welcomed.

Thank you in advance for your contributions!
