Description
Galactic cosmic ray (GCR) models have been developed by NASA, ROSCOSMOS and the European Space Agency (ESA) to provide fluxes for Hydrogen and heavy ions up to Iron over a broad energy range, while remaining computationally fast so that they may be used in an operational setting. The methodology behind the NASA Badhwar-O'Neill model (O’Neill, Golge, and Slaba 2015), the ESA DLR model (Matthia et al. 2013), and the ROSCOSMOS ISO model (Nymmik et al. 1992, 1994, and 1996) and their new SINP model (Kuznetsov, Popova, and Panasyuk 2017) will be described. These models are widely used by the radiation community to estimate the GCR particle environment at 1 AU, accounting for changes in flux due to solar modulation.
