Rainfall in the Greater and Lesser Antilles: Performance of five gridded datasets on a daily timescale

The studied region is the Greater Antilles (Cuba, Hispaniola, Jamaica and Puerto Rico) Lesser (Southern part of Caribbean arc). performance MSWEP, CHIRPS, PERSIANN-CDR, ERA-5 GPM IMERG were evaluated to highlight their qualities shortcomings guide researchers in choice these rainfall datasets use for hydro-meteorological applications this study area. Five quantitative (RMSE, KGE his three components) qualitative (POD, FAR CSI) statistical metrics are used evaluate amount detection capacity datasets. Heavy percentiles calculated assess ability estimate rare extreme rainfall. MSWEP performs well most recommended research. CHIRPS PERSIANN-CDR estimating annual seasonality research on water resources management (irrigation, energy production, etc.). also heavy events. have a good capture wet dry days determination climatic or atmospheric sciences applications. However, bias reduction methods gridded advised before due low high RMSE.
