      <ResourceName>IMP 8 Goddard Medium Energy (GME) 30-min energetic particle rates and fluxes</ResourceName>
      <ReleaseDate>2021-04-27T15:38:11Z</ReleaseDate>
      <Description>This CDAWeb-accessible data set contains 30-minute,
spin-averaged count rates and fluxes, and their statistical uncertainties,
of energetic particles from the IMP8 GME experiment.  Included are fluxes
of: protons in 30 energy bins from 0.88-1.15 to 327-485 MeV; alpha particles
in 21 energy bins from 1.14-1.36 to 63.3-81.0 MeV/n; and 0.3-18 MeV electrons. 
Also included are count rates for each of 7 sensors and for 11 multi-sensor
coincidence modes.  Proton and alpha particle fluxes, for every other energy bin, are given at the FTPBrowser and MSSP interfaces identified below.</Description>
