SPEI-GD: The first global multi-scale daily SPEI dataset for 1983-2020
The global daily SPEI dataset (SEPI-GD) at 0.25° spatial resolution form 1982 to 2021. This depository includes the five files of the daily SPEI data with five time scales (5, 30, 90, 180, and 360 days). The calculation based on ERA5's precipitation and Singer's potential evapotranspiration.

This depository includes the five files of the daily SPEI data with five time scales (5, 30, 90, 180, and 360 days). The calculation based on ERA5’s precipitation and Singer’s potential evapotranspiration. All data are geographic latitude-longitude projection and NetCDF format.
