%X The dataset is based on ERA5-Land land reanalysis data produced by the European Centre for Medium-Range Weather Forecasts (ECMWF) (data access URL: https://cds.climate.copernicus.eu/datasets/reanalysis-era5-land). ERA5-Land has a native spatial resolution of 0.1° × 0.1° (approximately 9 km) and an hourly temporal resolution. Data covering Tajikistan and the surrounding grid were extracted for 1950–2023, with the core calculation window extending from 1 October 1950 to 30 September 2024. Snow water equivalent, total precipitation and snowfall were used to derive the snow-drought products. The approximate study-area extent is 36°40′–41°05′N and 67°31′–75°14′E, whereas representative NetCDF files store a wider regular latitude-longitude grid of 35.0°–42.0°N and 66.0°–76.0°E. The study-area vector files use the WGS 1984 geographic coordinate system.
