To track space weather models’ progress and performance over time, the Community Coordinated Modeling Center (CCMC), together with NASA’s Living with a Star program, has initiated an extensive model validation and assessment efforts involving a community of space environment experts, model and application developers, data providers, forecasters and end-users of space weather products and services (https://ccmc.gsfc.nasa.gov/assessment/). The Radiation and Plasma Effects Working Team deals with five different subtopics: Surface Charging from 10s eV to 40 keV electrons, Internal Charging due to energetic electrons from hundreds keV to several MeVs. Single Event Effects from solar energetic particles (SEPs) and galactic cosmic rays (GCRs) (several MeV to TeVs), Total Dose due to accumulation of doses from electrons and protons in a broad energy range, and Radiation Effects from SEPs and GCRs at aviation altitudes
