摘要：

The EISCAT UHF radar was used to record high-resolution measurements of D-region electron density profiles during periods of energetic electron precipitation. Two sudden onsets in precipitation are studied in detail. The events occurred on 23 August 1985 in the post-midnight and evening sectors. The electron spectra deduced from the measurements indicate that each onset is associated with a complex influx of soft and hard energy particles. Examples are given of periods when the EISCAT radar measured significant variations in electron density even when the riometer system recorded no activity. © 1990.
