What s new in terms of AR Modeling? Integrated tools for generating data-driven chromospheric models Assignment to each photospheric pixel of vertical 1D adaptive height step chromospheric models (Fontenla et al. 2009) Integrated tools for generating coronal models User defined closed loops heating functions Assignment of voxel-dependent DEM distributions to compute EUV emission from TR and chromosphere (EBTEL- Klimchuk et al. 2008) Assignment of densities and temperatures derived from the moments of the DEM distributions Generation of Microwave, EUV, and soft X-ray maps based on the combined chromospheric and coronal models Ability to import numerically defined chromo and coronal models and compute MW, EUV, and X-ray synthetic emission maps Upgrade of the SSW GX_Simulator package coming this summer
