Chicago and UNH. There are fluxes of electrons in three energy bins: 0.7-2.0, 2-12, 12-50 MeV. These fluxes were generated at GSFC/SPDF from count rates accessible from UNH.

Simpson, the original CRNC PI, and Clifford Lopate/UNH, current PI. spase://SMWG/Person/Clifford.Lopate PrincipalInvestigator Readme file at SPDF https://spdf.gsfc.nasa.gov/pub/data/imp/imp8/particles_uchi/hourly/electrons/aareadme.txt Comprehensive data descriptive file https://spdf.gsfc.nasa.gov/pub/data/imp/imp8/particles_uchi/15min_asci/voldesc.sfd SFDU-formatted file describing the CRNC instrument and the 15-min data set of count rates and pulse height data from which the hourly rates data set was created. Division of hourly rates by geometric factor and energy band widths yielded the hourly fluxes. spase://VEPO/NumericalData/IMP8/CRNC/Electrons_PT1H spase://VSPO/NumericalData/IMP8/CRNC/Electrons_PT1H spase://SMWG/Repository/NASA/GSFC/SPDF Online Open FTPS from SPDF (not with most browsers) ftps://spdf.gsfc.nasa.gov/pub/data/imp/imp8/particles_uchi/hourly/electrons/ ftp access to electron-specific subdirectory holding annual ASCII files HTTPS from SPDF https://spdf.gsfc.nasa.gov/pub/data/imp/imp8/particles_uchi/hourly/electrons/ In CDF via HTTP from SPDF FTPBrowser https://omniweb.sci.gsfc.nasa.gov/ftpbrowser/imp_chi_crnc_1h.html Subset, plot and list fluxes of protons, alpha particles and electron, and count rates of heavies, via FTPBrowser Text 0.5 MB P1Y Acknowledge C.
