LANL Daily-averaged electron fluxes from the Synchronous Orbit Particle Spectrometer (SOPA)

Published by JGR | National Aeronautics and Space Administration | Catalog Last Checked: September 09, 2026 at 12:40 AM | Dataset Last Updated: September 07, 2026
Daily-averaged electron fluxes from the Los Alamos National Laboratory (LANL) Synchronous Orbit Particle Spectrometer (SOPA) Daily averages from each geosynchronous satellite available on any given day were merged into a single, uniform daily average. Data span 22 September, 1989 through 31 December, 2009. Data are log(flux) with flux in units of electrons /(cm^2.s.sr.keV). The original SOPA data channels have been fit to a bi-Maxwelian spectra. Fluxes are evaluated at virtual "channels" for fixed energies (i.e. not for an energy passband or integral thresholds) [see 2010JA015735 _LANL_Data_and_Processing for details] (2010ja015735-readme.txt)
