Space Weather research programs began around the world in the 1990's. Presently, three larger research groups are modeling key portions of the solar-terrestrial environment (i.e. solar wind).
These groups are (i) Center for Integrated Space Weather Modeling (CISM) at Boston University (ii) the Center for Space Environment Modeling (CSEM) at the University of Michigan and (iii) the Solar-Interplanetary-Geomagnetic (SIGMA) group of the State Key Laboratory at the Chinese Academy of Sciences. The models developed by the three group are summarized as follows:
A. Combination of kinematic and numerical model: Corona-Heliosphere (CORHEL) model
B. Self-Consistent magnetohydrodynamic models
B.1. SWMF (Space Weather Modeling Framework) BATS-R-US code
The SWMF integrates numerical models of the Eruptive Event Generator (EE), Lower Corona (LC), Solar Corona (SC), Inner Heliosphere (IH), Outer Heliosphere (OH), Solar Energetic Particles (SEP), Global Magnetosphere (GM), Inner Magnetosphere (IM), Radiation Belt (RB), Polar Wind (PW), Ionosphere Electrodynamics (IE) and Upper Atmosphere (UA) into a high-performance coupled model (Toth et al. 2012).
B.2. SWIM (Space Weather Integrated Model: SIP-CESE-MHD Code
The numerical code for SWIM is based on the space time conservation element and solution element (CESE) method. The SWIM system is a framework for integrating and running various space weather models.
It provides researchers an uniform environment to integrate the models of different spatial regions into a workflow that prepare the observational data and then analyzes and visualizes the output of the models. SWIM is programmed by using a combination of languages: C, FORTRAN and Python.
