Abstract:
In order to provide actionable information for the engineering and space weather operation communities, standardized validation of current state-of-the-art space environment models' capabilities to produce the most pertinent quantities required for impact assessment have to be carried out. In this presentation, we show the models that are currently available or in the process of being installed at the Community Coordinated Modeling Center (CCMC) relevant to the specification of the radiation environment (both from energetic electrons and energetic protons/ions) in the near-Earth region (e.g., possible internal charging effects resulting from radiation belt electrons and radiation effects at aviation altitudes due to GCRs and SEPs) and initial steps taken towards multi-purpose (including user-oriented) model validation efforts for both historical event-based and realtime modes. Such validation is needed for both science advancing and operational modeling capability building purposes. Measurements from ARMAS (for aviation radiation models), and Van Allen Probes & GOES (for radiation belt electron models) will be the primary source for model validation.
