NOAA SWPC's Operational Geospace Model Performance during Earth-Affecting Events
Abstract
The Geospace model was first transitioned into real-time operations at the NOAA Space Weather Prediction Center (SWPC) in October 2016 and has been upgraded once since going operational. The Geospace model is a part of the Space Weather Modeling Framework (SWMF) developed at the University of Michigan, and the model simulates the full time-dependent 3D Geospace environment (Earth's magnetosphere, ring current and ionosphere) and predicts global and local space weather parameters such as induced magnetic perturbations in space and on Earth's surface. The current version of the Geospace model uses three coupled components of SWMF: the BATS-R-US global magnetosphere model, the Rice Convection Model (RCM) of the inner magnetosphere, and the Ridley Ionosphere electrodynamics Model (RIM). In the operational mode, SWMF/Geospace runs continually using real-time solar wind data from a satellite at L1, either DSCOVR or ACE. We present an analysis of the overall performance of the Geospace model during the Earth-affecting events that occurred since the Geospace model went operational. We also use past large Earth-affecting events to evaluate how well the current operational version of the model would have performed during enhanced storm periods.
