Solar Proton Fluxes
To study the impact of solar proton events (SPEs), solar proton flux data from 1963 to 2019 (updated June 11, 2020) and a methdology to derive HOx and NOx production rates are provided by Charles Jackman. A description of how the data set was produced as well as a description about the structure of the data can be found here.
Data is available as a single tar.gz file (IonPair_1963-2019.tar.gz).
As of 2018 both the old (IonPair_Year-YYYY.dat, daily average ionization rates on pressure coordinates from Solar Proton Events given in #/cm+3/s) and new (IonPair-gm_Year-YYYY.dat, proton IPR daily averages on pressure coordinates in #/g/s) format are included in the tar file above, covering all years from 1963 to 2019.
