Abstract

An attenuation correction procedure is proposed and evaluated by simulations using raindrop size distribution obtained from ground-based disdrometer measurements. The results show that under certain conditions it is possible to retrieve C-band reflectivity factor (Z _H) and differential reflectivity (Z_DR) radar observables affected by attenuation along rain-filled propagation paths. Rainfall rates estimated from Z _H and Z_DR with and without attenuation correction are compared to determine the effects of attenuation and the capability of the correction procedure to account for it
