Abstract :
The theoretical formula for the relationship between rain attenuation and depolarisation proposed by Nowland et al. is improved by calculating the forward-scattering amplitudes of the Pruppacher¿Pitter type raindrops at 22 frequencies from 10 to 40 GHz. The dependence of the relation on frequency and on raindrop-size distributions is discussed.
