Abstract:
The GEM Metrics and Validation Focus Group has been conducting an Ultra-Low-Frequency (ULF) wave modeling challenge using monochromatic and white-noise solar wind pressure drivers. Using methodology similar to Claudepierre et al. (2010), MHD simulations performed by the SWMF, OpenGGCM and GUMICS models at the Community Coordinated Modeling Center (CCMC) are presented in comparison to LFM model outputs used in the publication and performed at the CCMC. We discuss the effect of inner (near-Earth) boundary conditions on the model results. Event simulations compared to ground-based and in-situ observations will eventually decide which boundary conditions are most realistic.
