Abstract :
Three-parameter distribution functions, gamma and lognormal, are used to describe the sizes of raindrops in Calcutta. The three parameters for a drop size distribution are obtained by solving three nonlinear equations formed with three measurements, namely rain rate and rain attenuations at millimetre and optical wavelengths. The two distribution models are compared by employing rainfall parameter estimation methods
