IRENE-AE9/AP9/SPM: Radiation Belt and Space Plasma Specification Models Air Force Research Laboratory (AFRL)

IRENE-AE9/AP9/SPM is a new set of models for the fluxes of radiation belt and plasma particles in near-Earth space for use in space system design, mission planning, and other applications of climatological specification. The suite is designated International Radiation Environment Near Earth (IRENE) with current component models denoted AE9, AP9, and SPM for energetic Electrons, energetic Protons, and Space Plasma Model, respectively. These models are derived from 45 data sets measured by satellite on-board sensors. The data sets have been processed to create maps of the particle fluxes along with estimates of uncertainties from both imperfect measurements and space weather variability. Users can obtain statistical confidence intervals, e.g. the median and 95^th percentile, for fluxes and derived quantities, supporting design trades.
