The Space Environment Monitor – NPOESS (SEM-N) is the primary instrument for 5 Environmental Data Records (EDRs). SEM-N is the only space weather sensor on NPOESS.
SEM-N is comprised of the Special Sensor J5 (SSJ5) for detection of low-energy particles, the Energetic Particle Spectrometer (EPS) for medium-energy particles, and omni-directional detectors for high-energy particles. In concert, these sensors are capable of providing measurements of the energy spectrum and directional distribution of charged particle fluxes in the vicinity of the spacecraft. The measurements are indicative of the population of the Earth’s radiation belts and of charged particle precipitation phenomena resulting from solar activity.
