Abstract

Multiparameter radar measurements were made during a heavy rainfall event accompanied by hail in Colorado. Rainfall rates (R) and accumulation for this event were estimated using S-band specific differential phase (K_DP), effective reflectivity factor (Z _H), and X-band specific attenuation (A_H3). These estimates were compared with measurements from a ground based raingage. Both R-K_DP and R-A_H3 relations were in good agreement with the raingage data, i.e., less than 10% difference in the rainfall accumulations. The R-Z relation produced similar results only when Z_H was truncated at 55 dBZ. This study demonstrates the potential of K_DP for estimating rainfall rates in severe storms that may have rain-hail mixtures
