Daily soil moisture mapping at 1-km resolution based on SMAP data for areas affected by desertification in Northern China

Areas affected by desertification in North China, which are very sensitive to SM, were selected as the study area. The downscaled soil moisture with a resolution of 1 km on a daily scale based on 36km SMAP soil moisture data from 2015 to 2020 was produced.

选取中国北方受荒漠化影响且对土壤湿度（Soil Moisture，SM）高度敏感的区域作为研究区。基于2015年至2020年的36公里分辨率SMAP土壤湿度数据，生成了日尺度下1公里分辨率的降尺度土壤湿度数据集。
