*************************** ** THE GEM MESSENGER ** *************************** Volume 19, Number 17 June 4, 2009 ---------------------------------------------------------------------------- Solicitation of Contributions to the "Space Radiation Climatology (SRC)" Focus Group at the GEM 2009 Summer Workshop ---------------------------------------------------------------------------- From: Paul O'Brien (paul.obrien [at] aero.org) Geoff Reeves (reeves [at] lanl.gov) The Space Radiation Climatology Focus Group will host a joint meeting with the Next Generation Radiation Specifications Consortium (NGRSC). NGRSC- focused sessions will occur on Wednesday, and GEM-SRC focused sessions will occur on Thursday. See http://www.virbo.org/GEM_NGRSC_2009 for more information. The NGRSC focus is development of radiation specification models to replace the out-of-date AE-8 and AP-8 models. The new models will improve upon AE-8 and AP-8 by being more accurate and more capable. New capabilities will include worst case environments and extended particle energy coverage. These new capabilities will help address spacecraft charging and surface dose effects which are not addressed by the current generation of specification models, except in select orbits. The workshop consisted of about 25 participants from Aerospace, Air Force Research Lab, Los Alamos National Lab, NOAA, ONERA (The French Aerospace Lab), Naval Research Lab, UCLA, and the University of Texas. Workshop presentations typically include updates on satellite particle radiation data inter-calibration, statistical models and methods, and data assimilation. Support for this effort comes from a wide array of sources, including the NRO's Proton Spectrometer Belt Research (PSBR) program and NASA's Living With a Star (LWS) program, NSF's Geospace Environment Modelling (GEM) program, and The Aerospace Corporation's IR&D program. Wednesday AM: NGRSC Project Updates (I) This schedule will be, if anything, more workshoppy even than GEM. We will try to allocate about 20-30 minutes of open discussion time per presentation. Talks in this session include AE9/AP9 and LANL/DREAM project updates. Wednesday PM1: NGRSC Project Updates (II) Talks in this session include Aerospace and (possibly) ONERA-DESP/CRATERRE project updates Wednesday PM2: Tools Updates et Cetera Talks in this session include updates of IRBEM-LIB, intercalibration methodology, fast L*, and the inversion library. Thursday AM: Recent science results from long-term simulations and data analysis Chair: O'Brien. Thursday our focus changes to more traditional GEM workshop questions of science, methods, and coordination of future work. Talks scheduled so far: Weigel, Shprits, O'Brien Thursday PM1: Implementation and methodology lessons learned Chair: Shprits Talks scheduled so far: Ni, Kondrashov Thursday PM2: Data/reanalysis sharing and future plans Chair: Weigel Highlight: Themis SST overview by the PI, Larson. Talks scheduled so far: Weigel, Chen, Denton +-------------------------------------------------------------------------+ |To subscribe GEM Messengers, send an e-mail to | | with the following command in the body of your e-mail message: | | subscribe gem | |To remove yourself from the mailing list, the command is: | | unsubscribe gem | | | |To broadcast a message to the GEM community, please contact Peter Chi at | | | |Please use plain text as the format of your submission. | | | |URL of GEM Home Page: http://aten.igpp.ucla.edu/GemWiki | |Workshop Information: http://www.cpe.vt.edu/gem/index.html | +-------------------------------------------------------------------------+
