UNCCD联合国防治荒漠化公约：2024年全球沙尘暴源底图（英文版）

This technical brief describes the method by which maps were created to identify potential sources of sand and dust storms. It employs global datasets for four indicators to estimate the extent of source potential and derive source intensity values: (i) soil texture (proportion of sand, silt, and clay), (ii) soil moisture (absolute minimum value), (iii) soil temperature (absolute maximum value), and (iv) land cover (bare land fraction). The Global Sand and Dust Storm Source Base Map, a visual
