Overview

This package gets, processes, and analyzes data from the Responsive Environmental Assessment Commercially Hosted (REACH) dosimeters. Built by the Aerospace Corporation and flown on 32 Iridium NEXT spacecraft, REACH provides global, low-latency monitoring of space weather hazards, including total dose, internal charging, and single-event effects. Across the constellation, 64 dosimeters spanning six sensor types which together provide high-cadence global measurements of particle populations from about 100 keV to 2.5 MeV electrons and about 1 MeV to 50 MeV protons.
