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 (ZDR) radar observables affected by attenuation along rain-filled propagation paths. Rainfall rates estimated from Z H and ZDR with and without attenuation correction are compared to determine the effects of attenuation and the capability of the correction procedure to account for it
