Data sets

The ERA-Interim reanalysis dataset ECMF https://www.ecmwf.int/en/forecasts/datasets/reanalysis-datasets/era-interim

GPM PR on TRMM Reflectivity, Precipitation Characteristics and Rate, at Surface and Profile L2 1.5 hours V06 Tropical Rainfall Measuring Mission https://doi.org/10.5067/GPM/PR/TRMM/2A/06

Short summary

Typhoon (TY) and non-typhoon (NTY) rainy days in northern Taiwan summer seasons showed more large drops on NTY than TY rainy days. Relatively higher convective activity and drier conditions in NTY than TY lead to variations in microphysical characteristics between TY and NTY rainy days. The raindrop size distribution and kinetic energy relations assessed for TY and NTY rainfall can be useful for evaluating the radar rainfall estimation algorithms, cloud modeling, and rainfall erosivity studies.
