On the conversion of a 3-hour integration time rain rate into one minute rain rate for forecast of attenuation due to rain

Abstract

Degradation of satellite signal due to rain at Ku- band and higher frequencies are of much importance to the radio science community. This calls for a continuous effort in the development of a 1-min rain rate conversion model from 180-min (3 hours) integration time which would be helpful in the utilization of such data in the generation of 1-min rain rate towards rain attenuation calculation from the available attenuation models. This paper has therefore presented a formula that converts a 180-min (3 hours) rain rate to its 1-min equivalent rain rate.
