Correlation between Sudden Cosmic Noise Absorption and Solar Radio Bursts observed at Five Microwave Frequencies

Abstract

THE 10.7 cm index of solar activity has been used for many studies of solar–terrestrial interactions. The principal reason for this is that highly accurate data extending back to 1947 are available. The present availability of accurate information at other microwave frequencies makes it possible to determine the relative effectiveness of these frequencies as indices of solar–terrestrial relations.
