Post Stabilization Ionization Level Predictions. Volume III of the Calendar Year 1975 Annual Report to the Defense Nuclear Agency.
Abstract
Patches of ionized air produced by the passage through the atmosphere of beta radiation emitted from nuclear debris clouds pose a potential threat to satellite communications. The distribution of the debris and the consequent ionization has been shown to be strongly a function of the mesospheric wind fields. Observational data for these wind fields is shown, upon analysis, to be inadequate for systems application and theoretical models have been developed to remedy this. The circulations in the upper atmosphere are driven by the time-dependent influx of solar radiation which is represented by a heating function used as input to the general circulation models. An improved heating function has been obtained and included in the NRL linear model, results for which are presented. Results obtained from improvements in the NRL program for the simulation of solar tidal influences are also presented. Finally, a computer program for predicting beta induced electron density distributions at any time after a nuclear burst is described. The program is suitably efficient for systems applications.
