SEM / Total Energy Detector
To measures proton and electron fluxes at platform level
Eight electrostatic analyzers and pulse height discriminators operating in two ranges: 0.05-1 keV and 1-20 keV, each measurement independently for electrons and protons.
Part of the packages named SEM (Space Environment Monitor) until NOAA-14, and SEM/2 (Space Environment Monitor - 2) from NOAA-15 onward and on MetOp
N/A (in-situ measurement in the platform environment)
