HF/VHF Absorption in the Disturbed D Region.

摘要

Absorption data obtained during the November 2-5, 1969 solar proton event at 36 MHz (ordinary and extraordinary waves), 18 MHz, and 9 MHz for four rocket flights plus 30-MHz riometer data are shown to be in good accord with theory. Factors influencing the precision of the results are discussed. (Author)
