SMAP L3 Radiometer Global Daily 36 km EASE-Grid Soil Moisture, Version 4

This Level-3 (L3) soil moisture product provides a composite of daily estimates of global land surface conditions retrieved by the Soil Moisture Active Passive (SMAP) passive microwave radiometer. SMAP L-band soil moisture data are resampled to a global, cylindrical 36 km Equal-Area Scalable Earth Grid, Version 2.0 (EASE-Grid 2.0).本三级（Level-3, L3）土壤湿度产品为由土壤湿度主动被动（Soil Moisture Active Passive, SMAP）被动微波辐射计反演得到的全球陆面状况每日估算值合成产物。其中SMAP L波段土壤湿度数据被重采样至分辨率为36公里的全球圆柱等面积可缩放地球网格2.0版（EASE-Grid 2.0）。
