SMAP and Sentinel-1 data of the Rhine basin

SMAP L3, corresponds to high-resolution satellite soil moisture in (m3 m-3) from active and passive sensors. This dataset can be useful to perform data assimilation of soil moisture with Delft-FEWS system for hydrologic forecasting of the Rhine basin. This will improve the accuracy of the discharge predictions because of the improvements on the states of soil moisture. The Sentinel-1 dataset corresponds to high-resolution soil moisture (%) from a passive sensor. This dataset can be used for data assimilation too, but the improvements are not as good as SMAP.

SMAP L3 数据集对应源自主动与被动传感器的高分辨率卫星土壤湿度（单位：立方米每立方米，m³·m⁻³）。该数据集可用于结合Delft-FEWS系统开展莱茵河流域水文预报的土壤湿度数据同化工作。此举可通过优化土壤湿度状态，提升径流预报的精度。Sentinel-1 数据集对应源自被动传感器的高分辨率土壤湿度（单位：百分比，%）。该数据集同样可用于数据同化，但其效果不及SMAP L3数据集。
