Abstract

A new version of the ONERA GREEN model (GREEN V3) is in development, with a focus on low-energy proton fluxes (1-10 MeV). Newly available measurements of the magnetosphere population of these particles make a revision of the GREEN model timely. Measurements from the RBSPICE instrument on the dual Van Allen Probes spacecraft and from the SEM2 instrument on the NOAA-POES spacecraft have been used to construct a proton flux model in this energy range. In order to take into account the dependence on the solar cycle of proton fluxes in the radiation belts, the correlation between those fluxes and the F10.7 solar radio noise has been studied. This paper describes the method used to estimate the proton fluxes between $\boldsymbol{\mathrm{L}^{\ast}=2}$ and $\boldsymbol{\mathrm{L}^{\ast}=6}$ for GREEN V3. Only the proton energy range 2.5-6.9 MeV is shown here but a larger energy range (1-10 MeV) has been studied.
