Analysis of the Drift of the South Atlantic Anomaly From ICARE and SEM-2 Flight Data

This article presents the study of the drift of the South Atlantic Anomaly (SAA) based on data coming from the radiation monitor ICARE-NG. This instrument was integrated on several low earth orbit (LEO) satellites such as JASON 2 and JASON 3. NOAA-15 data are also studied to compare and confirm ICARE-NG measurements. Twenty years of data have been used for this article. The evolution of the maximum proton flux detected, and the SAA area and centroid of the SAA have also been investigated.
