Correlation of Radar Echoes from the Aurora with Satellite-Measured Auroral Particle Precipitation

Abstract

The characteristics of auroral particle precipitation as measured during 14 passes by the Lockheed OV1-18 satellite over Alaska have been compared with radar aurora simultaneously detected at 139 and 398 MHz beneath the satellite orbit. The radar aurora were measured using the SRI auroral radar located at Homer in southern Alaska. The satellite measured precipitation of protons with energies above 10 keV and precipitation of electrons with energies above 800 eV. All measurements were made near local midnight while the E-region was in darkness.
