Nonstationarity Standardized Precipitation Evapotranspiration Index (NSPEI) dataset

The NSPEI dataset contains three types of data, one is based on meteorological station observation data, the second is based on ERA5 grid data, and the third is based on CMIP6 grid data. The dataset with timescales of 1–12 months has been archived in the Network Common Data Form (NetCDF) format. The monthly NSPEI has a spatial resolution of 0.25◦ from 1980 to 2020.
