  "description": "Daily-averaged electron fluxes from the Los Alamos National Laboratory (LANL) Energetic Spectrometer for Particles (ESP) 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) [see t 2010JA015735 _LANL_Data_and_Processing for details]",
