FG9-Space Radiation Climatology at Fall AGU 2007
1. GEM 2007 Mini Workshop at Fall AGU
Prior to the 2007 Fall AGU Meeting (10-14 December) we have the opportunity to gather and discuss the scope of our focus group and our strategy for the next few years. The 2007 GEM Mini-Workshop is taking shape, and we will likely be given a 2-hour time slot on the afternoon or evening of Sunday 9 Dec. At the GEM workshop the scope of our working group was left somewhat hanging, and the steering committee has not chosen to impose a scope on us. Therefore, we still need to resolve which phenomena our focus group shall include (radiation belt, ring current, and plasmasphere), and in what proportion.
The mini workshop agenda can be found at the GEM Workshops Homepage
2. FG9 Related Talks and Posters at Fall AGU
At the upcoming Fall AGU Meeting 10-14 there will likely be many talks and posters relevant to FG9. Please add your talk to the list at http://virbo.org/wiki/index.php/GEM2007mini or send email to paul.obrien-at-aero.org. We will distribute this list in hardcopy form at the GEM Mini-Workshop.

3. Geoff Reeves's Notes from FG9 Mini Workshop Session
3.1. Notes during Paul’s talk
Long term plasmasphere data from TEC may be available. Very appropriate for DA analysis
CRRES and AMPTE – can they be used even though they are short-term
Ring Current/Plasmasphere – how can we get DA applied? Can we use POLAR?
Would it be useful to collect climatology and reanalysis data sets on the Wiki? Would they be used?
3.2. Possible topics for the GEM Summer 2008 workshop
• what long-term variables are in data sets we know about? E.g. solar wind velocity, Dst, GOES >2 MeV, POLAR, SAMPEX
• How do we better connect ground-based and magnetospheric data sets
• Numerical techniques for discovering long-term variability (Yuri “volunteered”)
• Reanalysis over a (near?) solar cycle. Mike Liemohn has a solar cycle worth of storms (not quiet time) Our goal is to have a many-year DREAM run done by GEM. Sebastien/Reiner direct insertion model is done. Ganushkina volunteered to do SymH AsymH and global current systems. Onsager/Singer (?) B field perturbations at Geo
• How is our driven, coupled system different from terrestrial weather/climate modeling?
3.3. We need to better define FG9. Some possible thoughts were:
Our goal is “to discover the climatology of the inner magnetosphere on time scales of months to years.” (Discover was a key word)
Answering the question: What are the correlation scales (in Time, L, and energy) in the inner magnetosphere? Which parts are coupled/correlated and which parts are not? E.g. low energy at low L probably uncorrelated with high energy at high L but visa-versa are physically coupled.
Develop climate models that are different from event models. Go beyond the brute force approach of running current models for as long as we can.
Data/Model coupling: Data tells us what the models need to predict. Models tell us what we need to look for in the data. Could we test this with e.g. Tsyganenko for a full solar cycle vs various B-field data sets?
FG9’s goals stated this way provide a very clear coupling to some of the climatology in the SHINE community.
