Evaluation of GPM DPR rain parameters with north Taiwan disdrometers

In this study, Global Precipitation Measurement (GPM) mission Dual-Frequency Precipitation Radar’s (DPR’s) precipitation estimates are validated with long-term (2014-2022) measurements of seven Joss–Waldvogel disdrometers installed in north Taiwan. The results show that the GPM DPR shown greater performance when predicting the rain parameters in stratiform precipitation as opposed to convective precipitation. Furthermore, regardless of single and dual-frequency algorithm, the mass-weighted mean diameter had better agreement than the normalized intercept parameter.
