The GGCM Metrics and Validation focus group will have two sessions on 
Wednesday June 20 at this year's GEM Summer Workshop at Snowmass: 

10:30 am - 12:15 pm: "GGCM Modeling Challenge" (M. Kuznetsova, A. 
Ridley)

1:30 pm - 3:00 pm: "Measuring Models Climatologically" (T. Guild, L. 
Rastaetter, H. Singer) - session description in May 31 GEM Messenger. 

Tentative agenda and topics for discussions for the "GGCM Modeling 
Challenge" session:

1. Operational geospace model validation I: Evaluating geospace models 
   ability to forecast time-derivative of ground magnetic 
   perturbations dB/dt. Details of the project and dB/dt time series 
   derived from model outputs can be found at
   http://ccmc.gsfc.nasa.gov/challenges/dBdt/index.php (50 min)
   a.	dB/dt calculation from model outputs, visualization and 
        analysis tools/L. Rastaetter  
   b.	dB/dt metrics results/ A. Pulkkinen 
   c.	Discussion: Report/paper preparation. Next steps. 
2. Operational geospace model validation II: Geomagnetic activity 
   index (35 min)
   a.	NOAA SWPC needs for regional geomagnetic activity index 
        prediction/H. Singer  
   b.	Discussions: How to derive geomagnetic activity index from 
        model outputs. Metrics format selection 
3. Future planning  (20 min)
   a.	GGCM Metrics Challenges status.  
   b.	M&V Focus Group leadership transition.  Mid-term report 
        preparation.
   c.	GEM-CEDAR Challenge: Ionosphere Joule heating and Auroral

2. Call for Participation at 2012 GEM Workshop: 
   CCMC Tutorial Session on Wednesday at 3:30 pm
----------------------------------------------------------------------
From: Masha Kuznetsova <Maria.M.Kuznetsova at nasa.gov>    
 
The Community Coordinated Modeling Center (CCMC) is arranging a 
special CCMC tutorial session at the GEM summer Workshop (Wednesday, 
3:30 pm) to demonstrate CCMC tools and services and to collect 
feedback from the GEM Community. GEM Focus Group representatives are 
invited to discuss their FGs needs and present ideas on how the CCMC 
can support FGs projects.  David Berrios will present a tutorial on 
how to use a Java 3D advance visualization tool and the Integrated 
Space Weather Analysis system.  Lutz Rastaetter will demonstrate on-
line tools developed in support of community-wide modeling 
challenges.  Emily Hyatt, the winner of the CCMC Student Research 
Contest, will give a demo-presentation "How I used CCMC tools in my 
research".  Participants are encouraged to bring laptops for hands-on 
experience.
