Temporal and spectral signatures of a lightning-induced electron precipitation (LEP) burst observed on the S81-1 (SEEP) satellite are analyzed and compared with the predictions of a test particle model of the gyroresonant whistler-particle interaction in the magnetosphere. The flux to be detected by specific detectors on the low altitude (~220 km) satellite at L≂2.24 is calculated in terms of the integral counting rate as a function of time and in terms of the dynamic energy spectra during the initial ~300-ms precipitation pulse. For a whistler wave packet with frequency range 500 Hz to 6 kHz the dynamic energy spectra are found to depend sensitively on the electron angular distribution in the vicinity of the loss cone. In the case of a whistler wave originating in northern hemisphere lightning the maximum whistler-induced pitch angle scattering of electrons occurs near ~10 ¿S geomagnetic latitude. However, scattering occuring over the latitude range of ~20 ¿N to ~20 ¿S is found to be significant and contributes to the observed LEP pulse. The dynamic energy spectra of the LEP pulse and the temporal profile of the integral counting rate are consistent with the predictions of a test particle model of the gyroresonant scattering of the electrons by a whistler wave having an equatorial intensity at 6 kHz of ~200 pT. The measured LEP pulse pitch angle distribution is wider than that estimated on the basis of the test particle model. ¿ American Geophysical Union 1989
