Recent Updates to the Solar Particle Event Threat Assessment Tool (STAT)

The Solar Particle Event (SPE) Threat Assessment Tool (STAT) is a software suite that combines a state-of-the-art thermodynamic magnetohydrodynamic model (MAS) with a global energetic particle simulation (EPREM). STAT can be used to simulate the acceleration and transport of Solar Energetic Particles (SEPs) produced in specific events driven by large solar eruptions. STAT provides detailed diagnostics that allow analysis of the global properties of an event, as well comparisons of simulated SEP fluxes with multi-spacecraft in-situ data.In this presentation, we describe recent feature updates and improvements to the STAT model. These include algorithm improvements in the EPREM model, additional parameter options, the ability to simulate an SPE using multi-resolution CME simulation output generated by the on-demand CORHEL-AMCG framework hosted at NASA’s Community Coordinated Modeling Center (CCMC), and improvements to the post-processing of STAT output that allow more accurate comparisons to SEP in situ data.Research supported by NASA and NSF.
