Daily SPEI dataset in China from 1980 to 2100

The daily Standardized Precipitation Evapotranspiration Index (SPEI) dataset used the PM-CO2 model to calculate PET is with a spatial resolution of 0.5° × 0.5° from 1980 to 2100. This dataset investigates drought, focusing on the region of China, using simulations from five global climate models (GCMs) under three Shared Socioeconomic Pathways (SSP1-2.6, SSP3-7.0, and SSP5-8.5）participating in the Inter-Sectoral Impact Model Intercomparison Project (ISIMIP3b).
