Measurements and Applications
|
Space environment at platform level. Provides both directional (nadir and 90° from nadir) and omni-directional measurements. Directional: protons are measured in 6 bands in the energy range 0.03-6.9 MeV, electrons in thee bands in the range 30-300 keV. Omni-directional: proton energy in the ranges > 16 MeV, >35 MeV, > 70 MeV and > 140 MeV. 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
