The Virtual Enhancements – Solar Proton Event Radiation (VESPER) model is one of the latest efforts in the probabilistic modelling of solar particle radiation. VESPER produces differential proton flux time-series of virtual Solar Proton Events (SPEs) for arbitrary mission durations. These virtual SPEs are constructed by rescaling historical SPEs in a spectrally coherent way. A presentation on...
Recently a new SEP probabilistic model, VESPER, was introduced. It makes use of virtual time-series of proton differential intensities of particle events. This is in contrast to previous models like ESP, JPL, the SEPEM/VTM and SAPPHIRE that use peak flux and fluence distributions. Besides, the SEPEM statistical model for interplanetary missions uses the SEPEM helio-radial reference event list...
The PAMELA satellite experiment has recently provided accurate spectral measurements for 26 solar energetic particle (SEP) events occurring between December 2006 and September 2014. Observations cover the range between 80 MeV and 2 GeV, bridging the low-energy measurements from in situ space-based instruments and the high-energy data from the worldwide network of neutron monitors during ground...
