Call for participation in CEDAR-GEM Modeling Challenge Session at 2013 GEM 

We invite modelers, data providers, science and operational users of space 
weather models to participate in the GEM-CEDAR Modeling Challenge Session, which 
will be held during 2013 GEM Mini-Workshop on Sunday, December 8th 2013. The 
session details will be provided later, however it is suggested that you plan to 
arrive on Saturday (12/07/2013) since sessions usually start at noon.

Since the initiation of CEDAR-GEM Challenge 
(http://ccmc.gsfc.nasa.gov/challenges/GEM-CEDAR/index.php) during the Joint 
CEDAR-GEM Workshop in June 2011, the project focuses on various scientific and 
operational aspects of the performance of magnetosphere and ionosphere models 
and addresses challenges of model-data comparisons and metrics studies.  The 
studies done and topics discussed so far include
*  Poynting Flux/Joule Heating metrics study
*  Auroral oval boundary study
* MI coupling study:
** Role of drivers on Ionosphere/Thermosphere model results
** Tools for swapping drivers (e.g., high latitude electric potential, particle 
precipitation, penetration electric field)
*  Global TEC/NMF2/HMF2 metrics study
*  Ionosphere/Thermosphere climatology study
*  Model-Data comparison:
** How to quantify storm impacts on the ionosphere and thermosphere
** Ideas for real-time validation (e.g., IT parameters at ISS location)

In the session this year, we will discuss:
# Quantifying storm impacts on the ionosphere/thermosphere
# Status of community-wide tool for ionosphere drivers
# Model-data comparison for high inclination and polar orbiting satellites 
(e.g., ISS, DMSP, and etc.)

During the CEDAR-GEM Challenge Meetings at the 2013 Space Weather Workshop 
(April 15, 2013) and 2013 CEDAR Workshop (June 22-28,2013), there was a 
discussion on “How to quantify storm impact on the ionosphere and thermosphere”, 
and 8 physical processes 
for the study were suggested by Tim Fuller-Rowell.  We will first focus on three 
of the eight physical processes.

(1) Quantifying storm impacts on the ionosphere/thermosphere
* Process 1: Quantifying the storm energy input
** Increase in magnetospheric/ionospheric high latitude convection and auroral 
** Enhances in conductivity at high latitudes and NO production
** High latitude winds accelerated by ion drag
** Joule heating increase
** NO cooling IR radiation measured by SABER (∝ NO and T)
** Rate of temperature/density response and recovery
* Process 3: Build-up of plasma and structure at mid-latitude
** Validate TEC from GPS maps
** Validate in-situ Ne, slant TEC, or limb profile Ne from satellites
** Validate ground location Ne profiles with ionosondes
* Process 6: Onset/timing/evolution of neutral composition change
** Response and recovery of O/N2 (e.g., TIMED/GUVI)
** Movement of boundaries in O/N2 (e.g., TIMED/GUVI)

People are invited to present on the topics.

Next, we will discuss preliminary results and future plans of community-wide 
collaborative development of
<br>(2) Driver swapping tool for MI coupling study

We will also discuss
<br>(3) model-data comparisons for high inclination and polar orbiting satellite:
* ISS Geomagnetic Storm Studies (e.g., ISS Auroral Charging)
* Preparation for a new model/data comparison project
** Ne and Te at ISS locations (in 2012 and etc.)
Data will be available soon and we will discuss the priority of various time
