Rainfall erosivity maps over mainland China for near term and far term
Two key rainfall erosivity indexes, namely the annual average rainfall erosivity (R-factor) and the extreme storm EI30 with a 10-year return period (10-year storm EI) were projected for the mainland China. These projections encompassed two future periods (median: 2041-2065; end: 2076-2100) and considered two distinct emission scenarios (SSP1-RCP2.6 and SSP5-RCP8.5). Our analysis drew upon Multi-Model Ensembles (MMEs) generated from three CMIP6 Global Climate Models (GCMs): GFDL-ESM4, IPSL-CM6A-LR, and UKESM1-0-LL. To ensure the projected accuracy, bias correction techniques were applied to these model outputs by comparing with the state-in-art rainfall erosivity maps of China (Yue et al., 2022). Future rainfall erosivity during these two periods over mainland China are open downloaded as following.
