Abstract. The risk of water erosion on the Tibetan Plateau (TP), a typical fragile ecological area, is increasing with climate change. A rainfall erosivity map useful for understanding spatiotemporal pattern and identifying hot spots soil erosion. This study generates an annual gridded dataset 0.25∘ grid TP in 1950–2020. 1 min precipitation observations at 1787 weather stations 7 years hourly E...

Rainfall erosivity factor (R-factor) is one of the Universal Soil Loss Equation (USLE) input parameters that account for impacts rainfall intensity in estimating soil loss. Although many studies have calculated R-factor using various empirical methods or USLE method, these are time-consuming and require specialized knowledge user. The purpose this study to develop machine learning models predic...
