Rice Electron Precipitation Model

Data from the low energy electron experiment (LEE) on the AE-C and -D satellites have been used to determine the distribution of the energy flux of precipitating auroral electrons and their average energy for different levels of geomagnetic activity. The study is based on 30,407 individual measurements from January 1974 to April 1976. Tables of energy flux and characteristic energy were produced for four ranges of auroral electrojet indices (AE). Each table shows the variation with invariant latitude (30 bins between 50 and 88) and magnetic local time (24 bins between 0 and 24). Empirical relationships are used to produce similar tables for the Pedersen and Hall conductances. Robinson et al. (1987) have pointed out errors in the calculation of conductances in the Rice model. Improvements were suggested by Kamide et al. (1989).
