Historical and Projected Precipitation and Soil Erosion Data in Dianchi Basin

This dataset contains the gridded data used in Figures 2–8 of the associated study on extreme precipitation and soil erosion in the Dianchi Basin, China. The dataset includes: Historical precipitation data Corrected CHIRPS satellite precipitation (daily and monthly) for 2005–2024 Derived extreme precipitation indices (R95p, Rx1day, Rx5day, PRCPTOT, CSDI, SDII) for 1951–2024 GCM-based future precipitation projections Monthly precipitation under four SSP scenarios (ssp126, ssp245, ssp370, ssp585) Integrated using Dynamic Bayesian Model Averaging via Mixture of Experts (DBMA-MoE) Soil erosion data Historical average annual soil erosion rates (2005–2024) Projected monthly soil erosion changes under the four SSP scenarios for two future periods (2040s, 2060s) All soil erosion calculations are based on the RULSE model, driven by SDII and adjusted precipitation data File format: GeoTIFF (.tif), CSVUnits: Precipitation in mm; Soil erosion in t·ha⁻¹·yr⁻¹.Spatial coverage: Dianchi Basin, ChinaTemporal coverage: 1951–2100 (historical and projected) Usage note:These data can be used for reproducing the figures in the manuscript, further spatial analysis of precipitation and soil erosion, or validation of hydrological and erosion models.
