GEM Modeling Challenge

Summary

The GEM community has recognized that due to the maturity and the increasing complexity of the state-of-the-art global space weather models, there is a great need for a systematic and quantitative evaluation of different GGCM modeling approaches. In summer 2008 the GGCM Metrics and Validation Focus Group initiated the GGCM modeling Challenge. The goals of the Challenge:

  • Evaluate the current state of the space science models and track model improvements over time
  • Facilitate interaction between research and operation communities
  • Facilitate collaboration among modelers and data providers and research communities.
  • Facilitate further model improvement.

The project focuses on various scientific and operational aspects of GGCM model performance and addresses challenges of model-data comparisons and metrics studies (e.g., model output and observational time series preparation for comparison, measurement uncertainty, metrics selection).

Solar Wind Input

Comments on Solar Wind (SW) Data Availability

For Event 2, Event 3, Event 4 verified solar wind (SW) data (Level 2) are available at the ACE science center.

Click HERE to generate SW input data file with magnetic (ACE MAG) and plasma data (ACE SWEPAM) interpolated on 1 minute temporal grid using CCMC on-line tool. The CCMC SW input file generation tool allows to project data from the ACE position to the simulation box inflow boundary and/or to add a time shift. SW parameters in the generated input data file are provided in the following order:
Year Month Day Hour Min Sec Msec BXGSM[nT] BYGSM[nT] BZGSM[nT] VXGSM[km/s] VYGSM[km/s] VZGSM[km/s] N[cm^(-3)] T[Kelvin]

For Event 1 there were problems with ACE plasma instrument (SWEPAM). Click HERE [TXT] to download solar wind input file prepared by Aaron Ridley. SW parameters are provided in the following order:
Year Month Day Hour Min Sec Msec BXGSE[nT] BYGSE[nT] BZGSE[nT] VXGSE[km/s] VYGSE[km/s] VZGSE[km/s] N[cm^(-3)] T[Kelvin] .
Magnetic field components ( BXGSE, BYGSE, BZGSE) are from ACE MAG, velocity components (VXGSE, VZGSE, VZGSE) and temperature (T) are from ACE SWEPAM, and density (N) is from the Geotail plasma wave experiment. The data are projected to Xgse = 32 Re.
