Electron losses from the magnetosphere.
electronlossesfr00dewe.pdf (6.216Mb)Abstract
A semi-empirical method for modelling the loss of electron fluxes in the earth's magnetosphere
was developed. An equation for the integral-energy omnidirectional electron flux
as a function of time and magnetic field strength was derived from pitch-angle diffusion
theory.
This flux equation was the basis for a computer data-fitting program written at the
Air Force Weapons Laboratory (AFWL) to fit the AFWL Trapped Electron Daoa Base. The
program utilised a least-squares fit and incorporated random variations of the characteristic
exponential loss times about their initial values. Ad improved table of initial less times was
compiled for use with the program.
The derived flux model showed substantial agreement with the empirical data base.
Representative plots of computed flux over raw data are shown for L-values of 2.3 and 2.4.
