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]

"There are a number of caveats associated with these data. Primary cosmic rays may account for a substantial fraction of the observed counts. A significant secondary contribution is also implied, however there is currently
no modeling to suggest to what extent this contributes to the observed
counts. Some ESP channels appear to saturate at 4 x 10^4 counts/ s. The
reported flux levels should not be used as absolute measures: It is known
that ESP yields lower fluxes and harder spectra than SOPA, in the region of
overlap between the detectors. Calculation of spectra, for example, would
not be meaningful for this data set – especially as the data are daily averaged
and merged from several satellites." (Electronic supplement to "On the relationship between relativistic electron flux and solar wind velocity: Paulikas and Blake Revisited”)
