Predicting Riometer Absorption for Solar Radio Bursts. I. Correlations between Proton Spectra and Riometer Absorption,

Abstract

Observed riometer absorption A (in db) is correlated with the proton spectrum variable (log I (>10 MeV) + alpha log Rho), where I(>10 MeV) is the peak flux of protons with energies in excess of 10 MeV, Rho is a measure of the average energy of these protons and alpha is an adjustable parameter. Study of the major proton events (I(>10 MeV) > 100 protons / sq cm /sec/ ster since 1967 shows excellent correlations. Even when the average energy dependent factor is ignored (alpha=0), our approach provides better correlations than the usual square root relation; optimization over alpha further improves the correlations to r nearly equivalent to 0.97. A practical program for utilizing solar radio burst data for an early prediction of riometer absorption can now be developed by combining our previous studies on radio results from proton correlations with the proton results from riometer results reported here.
