A New High-Resolution Multi-Drought Indices Dataset for Mainland China; CHM_Drought

CHM_Drought，an innovative and comprehensive long-term meteorological drought dataset with a spatial resolution of 0.1° and data collected from 1961 to 2022 in mainland China. It features six pivotal meteorological drought indices: the standardized precipitation index (SPI), standardized precipitation evapotranspiration index (SPEI), evaporative demand drought index (EDDI), Palmer drought severity index (PDSI), self-calibrating Palmer drought severity index (SC-PDSI), and vapor pressure deficit (VPD), of which SPI, SPEI, and EDDI contain multi-scale features for periods of 2 weeks and 1–12 months.The dataset features a comprehensive application of high-density meteorological station data and a complete framework starting from basic meteorological elements (the China Hydro-Meteorology dataset, CHM).Global attributes:· Variable = SPEI-xx, SPI-xx, EDDI-xx, PDSI, SC-PDSI, VPD· Date format = NetCDF· Temporal Range = 1961-01-01 to 2022-12-31· Spatial Resolution = 0.1 degree· Spatial extent = 18°N–54°N, 72°E–136°E· Missing value = NA
