1. Summary of 2007 GEM Mini-Workshop at Fall AGU
At the 2007 Mini-Workshop at Fall AGU we discussed our plans for the
remainder of the FG9 years.
Paul O'Brien lead the discussion with a set of suggested "products" we
could provide to GEM. Paul's list was sorted roughly by ease of
completion, but Terry Onsager and others suggested we also ought to
prioritize by scientific impact.
Geoff Reeves stated that our primary scientific objective ought to be
to "Discover the climatology of the inner magnetosphere." This idea
went over well.
We also discussed how to organize the summer 2008 GEM workshop FG9
sessions. Some invited talks were suggested:
- A student tutorial on reanalysis and climatology (to give students
thesis ideas)
- What we already know about inner magnetosphere climatology.
- How do we characterize long-term climatology?
- Intro to data assimilation, principal component analysis, etc. (Yuri
Shprits)

2. Collecting reanalyses, climatologies, etc on-line
As a group we decided it was important to collect at least a list of
reanalyses, climatologies, and similar data sets. Bob Weigel has
tentatively agreed to host these data on ViRBO - assuming disk space
does not become an issue. Mike Wiltberger stated that we could
probably work something out with NCAR and/or NGDC for our really huge
data sets.
We know of the following reanalysis-like data sets:
- ONERA Salammbo electrons and protons: 11+ years, Sebastien Bourdarie.
Sebastien has stated that for the time being this data cannot be
widely released due to ONERA policy. Individual collaborations may
be possible. Sebastien.Bourdarie-at-onecert.fr
- LANL DREAM Outer Zone Reanalysis: full solar cycle should be done by
Summer GEM, Geoff Reeves.
- UCLA CRRES Outer Zone Reanalysis: entire CRRES mission, Yuri
Shprits.
- U. Mich. Ring Current: numerous 4-day runs, Mike Liemohn.
- Aerospace statistical electron reanalysis: 11 years, Paul O'Brien.
This data set will be released to ViRBO when version 2 is complete
(early-mid 2008).
- Aerospace Selesnick proton model: multiple solar cycles, Richard
Selesnick.
- SymH, AsymH, global current systems, Natalia Ganushkina.
- B-field perturbations at GEO, Howard Singer.

Over the holidays I reread your paper (O'Brien and Lemon, Space
Weather, p. S03007, 2007), and I would like to explore with you the
possibility of implementing your results for future analyses here
behind the fence. However, I first need to understand better what
you actually did. I think my confusion centers on your Figure 4 (c
and d). From the text, I would have expected that for nhp at 0530
LT, you would have found one set of three models (e.g., Kp, nhp at
5.5+/-2 h) that gave the best correlation with your in-sample data
(paragraph 12). But Figure 4 shows that each of your models was
"used" thousands of times. What am I missing? If this would be
easier to explain over the phone, I'd be happy to call you or you
could call me at your convenience. I'll be here today until ~3:30
Mountain Time.
Best,
Michelle
