China rainfall erosivity (2015–2023): A new annual dataset inferred from national hourly meteorological station records

This dataset provides a 0.1° gridded product of multi-year mean and annual rainfall erosivity (R-factor) for China, derived from quality-controlled hourly precipitation observations at 57,740 meteorological stations over the period 2015–2023. It includes bias-corrected (×1.871) multi-year mean annual rainfall erosivity (2015–2023) and annual rainfall erosivity for each year from 2015 to 2023 (uncorrected) in GeoTIFF format (WGS84, EPSG:4326). This dataset can support soil erosion assessment (e.g., RUSLE), hydrological modeling, land degradation studies, and climate change impact analysis.
