Abstract

This paper presents particle flux measurements (protons and electrons) obtained with the ICARE-NG detector on the JASON-2 orbit (1336 km alt., 66° incl.) for the period June 2008-Aug. 2010. At this altitude, the South Atlantic Anomaly is greatly broadened as compared to lower altitudes. Proton flux measurements are made in the range 27.5-290 MeV and electron flux in the range 1.6-3.6 MeV. A great care was taken to assess the influence of the satellite on the particle measurements. Comparison of measurements with the results of the AP8 MIN model are given for protons, taken into account environment anisotropy.
