Abstract
Atmospheric radio noise (ARN) also called static is caused by the naturally occurring intercloud electrical discharge in thunderstorms accompanying electric flashes in the Earth´s atmosphere. They are spread over a wide range of radio spectrum and their intensity bears an inverse ratio to the frequency. Their effects are significant up to 30 MHz which includes the broadcasting bands. In any radiocommunication system, noise sets a limit for the satisfactory reception of radio signals. The main aim of the paper is to draw comparisons between the measured values of average ARN levels in India, CCIR predicted values and those estimated by Kotaki and Katoh 1983 from thunderstorm activity data for India
