An update of the AE9/AP9/SPM radiation belt and space plasma specification model, Version 1.20.002, has been released. As in the prior releases in 2012 and 2013, this model suite provides estimates of trapped energetic electrons, energetic protons, and plasma, for use in space system design, mission planning, and other applications of climatological specification. It is based on 37 satellite-based data sets processed to create maps of the particle fluxes along with estimates of uncertainties from both imperfect measurements and space weather variability. These uncertainty estimates can be obtained as statistical confidence intervals, e.g. the median and 95 percentile, for fluxes and derived quantities, supporting design trades. Implementations of the legacy AE8/AP8 and CRRESELE/CRRESPRO models are available within the model suite. The SHIELDOSE2 code is used for dose estimation from the calculated fluxes. Orbit ephemeris may be generated using one of three orbit propagators, or may be directly supplied. The self-contained software package includes a Windows-based executable version of the model suite, accessible either by command line or graphical user interface, plus supporting documentation such as the users’ guide, validation results, and software license information.
