GOES-R Series Level 1b SEISS Magnetospheric Particle Sensor High Energy (MPS-HI) Product in Daily Aggregations

The GOES-R Magnetospheric Electrons and Protons: Medium and High Energy (MPSH) Product consists of fluxes of medium and high energy electrons and protons derived from in situ measurements of electron and proton count rates. The Magnetospheric Particle Sensor High (MPS-HI) makes these measurements. MPS-HI consists of ten solid state telescopes, five for electrons and five for protons, that define a 170-degree fan-like field-of-regard in the north-south plane. Differential and integral electron fluxes are reported at eleven energy bands from each electron telescope. Ten of the energy bands are evenly spaced logarithmically spanning from 50 keV to 4 MeV with differential electron flux being reported. The eleventh energy band collects electrons with energies greater than 2 MeV with electron integral flux being reported. In addition, differential proton fluxes are reported at eleven energy bands from each proton telescope. The eleven proton energy bands are evenly spaced logarithmically and range from 80 keV to 12 MeV. In addition, the product contains ionizing radiation doses in two energy deposition ranges, 50 keV to 1 MeV (low linear energy transfer, LOLET) and 1 MeV to 50 MeV (high linear energy transfer, HILET). The product also contains processing and data quality metadata, satellite state and location information, and data required for the generation of level 2 products. Measurement resolution is one second. NOAA's National Centers for Environmental Information (NCEI) has created these daily files by aggregating the official L1b files produced by the GOES-R Ground System. The granular L1b files each span 30 seconds of observations.
