Rain-induced attenuation effects on C-band dual-polarization meteorological radars

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/sub H/) and differential reflectivity (Z/sub DR/) radar observables affected by attenuation along rain-filled propagation paths. Rainfall rates estimated from Z/sub H/ and Z/sub 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.<
