全球0.1度陆地年降雨能量和降雨侵蚀力数据集(2015-2019年)

该数据集为全球0.1度陆地年降雨能量和降雨侵蚀力数据集，数据时间为2015-2019年。该数据集范围包括全球60S-60N纬度内陆地范围，0.1度分辨率的所有格网。该数据反映了全球降雨能量和降雨侵蚀力现状及其地域分布规律，以*.mat格式存储。该研究利用不同频率的雷达回波数据，基于格网雨滴微物理特征，建立了高时空分辨率的全球降雨动能和降雨侵蚀力计算模型，通过评估2015-2019年全球降雨能量、降雨侵蚀力及其偏差百分比，揭示了低收入国家普遍低估降雨侵蚀力的严峻现状。

This dataset is a global terrestrial annual rainfall energy and rainfall erosivity dataset spanning the years 2015 to 2019. Its spatial coverage encompasses all terrestrial grid cells within the latitude range of 60°S to 60°N with a 0.1° spatial resolution. This dataset reflects the current state and geographic distribution patterns of global rainfall energy and rainfall erosivity, and is stored in the *.mat format. This study developed a high spatiotemporal resolution global computational model for rainfall kinetic energy and rainfall erosivity using radar echo data at different frequencies based on grid-scale raindrop microphysical characteristics. By evaluating the global rainfall energy, rainfall erosivity and their percentage deviations during 2015–2019, this study revealed the severe reality that low-income countries generally underestimate rainfall erosivity.
