Description
Two papers presenting the (Solar Accumulative and Peak Proton and Heavy Ion Radiation Environment (SAPPHIRE) model and its implementation we published in 2018. The model deals with short- and long-term SEP environments in a way which is more coherent and consistent than previous approaches. It also leverages extensive work carried out in the processing of data and addressing caveats.
The SAPPHIRE model covers all SEP ions from 0.1 MeV/nuc to 1 GeV/nuc. It also introduces the concept of 1-in-n-year SEP events derived statistically to provide a common baseline for a series of spacecraft.
SAPPHIRE does not present include time series, the high-energy part is extrapolated from 250 MeV/nuc (for protons and lower for heavier ions) and the low-energy peak flux extrapolations (below 5 MeV) are not fully in-line with other in-situ observations.
This talk will briefly present SAPPHIRE and how it can be further evolved to fit in the IRENE framework.
