INFN AMS daily proton time dependent fluxes¶
Daily proton fluxes in cosmic rays were measured with the Alpha Magnetic Spectrometer aboard the International Space Station, from May 20, 2011 to October 29, 2019 (a total of 2824 days or 114 Bartels rotations) in the rigidity interval from 1 to 100 GV, based on 5.5×10^9 protons collected. Several Forbush decreases were also observed during the whole period, in connection with transient magnetic perturbations. The product provides these data as time-profiles from May 20, 2011 to October 29 2019 as a function of rigidity. In particular the daily proton fluxes are measured in 30 bins from 1.00 to 100 GV. The errors include statistics, time-dependent systematic errors and the total systematic error.
