CREME-96 Sol. Min (1977)

Model API name: creme-96-gcr

The GCR CREME96 model implemented in SPENVIS is for the solar-minimum GCR environment and corresponds with the GCR maximum last observed in 1986-87. The model is based on the model of Nymmik et al. (1992) and includes anomalous cosmic ray fluxes (visible for He, N, O and Ne around 10 MeV/nleon) derived from SAMPEX results.
