Geostationary Operational Environmental Satellite, R-Series (GOES-R) Space Environment In-Situ Suite (SEISS) Level 2 Products

The Space Environment In-Situ Suite (SEISS) is comprised of four sensors that monitor proton, electron, and heavy ion fluxes in the magnetosphere. These four sensors are the Energetic Heavy Ion Sensor (EHIS), the Magnetospheric Particle Sensors - High and Low (MPS-HI and MPS-LO), and the Solar and Galactic Proton Sensor (SGPS). There are two SGPS units on each satellite, one looking westward and one looking eastward. SEISS L2 data are used by NOAA’s Space Weather Prediction Center to drive the solar radiation storm alerts, based on NOAA’s space weather scales and the >2 MeV electron radiation belt alert, and to improve energetic particle forecasts.
These SEISS Level 2 (L2) data include several different products: one and five-minute averages of fluxes from MPS-HI, MPS-LO and SGPS; one and five-minute integral fluxes from SGPS; density and temperature moments from MPS-HI and MPS-LO; solar particle event detection and rate of rise; and linear energy transfer from EHIS heavy ions. Data are in netCDF-4 format.
