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

GOES-R SEISS MPS-HI L1b Data 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.

    Supplemental Information
    MPS-HI consists of ten solid state telescopes, five for electrons and five for protons. Collectively, the five telescopes per species, each with a 30 degree conical field-of- view, span a total angular range of 170 degrees in the Y-Z plane, arranged north-to-south in a fan. The central telescope has an anti-earthward look-angle parallel to the minus Z-axis (in spacecraft body-reference- frame coordinates). Neighboring telescope centers are separated by 35 degrees. The north-to- south order of telescope numbers is (3, 1, 4, 2, 5) for electrons and (1, 4, 2, 5, 3) for protons when the spacecraft is upright. The MPSH product's low linear energy transfer (LOLET) and high linear energy transfer (HILET) radiation dose measurements are obtained from a pair of dosimeters with 250 mil (0.635 cm, Dosimeter 1) and 100 mil (0.254 cm, Dosimeter 2) aluminum shielding, for a total of four dose products.
    Purpose 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. Differential and integral electron fluxes are reported at eleven energy bands in five angular look directions. The data will help users who wish to monitor solar energetic particle (SEP) events and research magnetospheric conditions. NESDIS produces GOES-R SEISS MPS-HI Level 1b products from GOES-R SEISS Level 0 source files. These output files span 30 seconds of one-second observations. NOAA's National Centers for Environmental Information (NCEI) then takes the 30-second files and aggregates them to produce daily SEISS MPS-HI L1b products. These daily files are intended to be more convenient for users than the original 30-second files.

    Processing Steps
    • The SEISS MPS-HI L1b Calibration Algorithm (SMHCA) produces the MPS-HI electron and proton fluxes. The MPS-HI raw count rates are first corrected for the dead-time effect. The proton count rates are assumed to be free from out-of-band contamination, based on pre-flight ground calibration activities. For the electron out-of-band contamination correction, the SMHCA uses proton fluxes from the SEISS SGPS-X sensor unit (in particular, from Telescope 3) to correct the highest energy electron channels. Finally, the dead-time corrected and contamination-corrected count rates for both protons and electrons are divided by geometrical factors to obtain differential fluxes for the differential channels, and integral fluxes for the integral channels.
