该数据集集合包含三个表面土壤湿度数据集以及辅助数据产品。主动(AMI-WS 和 ASCAT)和被动(SMMR、SSM/I、TMI、AMSR-E、WindSat、FY-3B、FY- 3C、FY3D、AMSR2、SMOS、GPM 和 SMAP)产品分别由卫星散射仪和辐射计土壤湿度产品组成。 图1 1991-2020土壤含水量异常值;图片来源:https://climate.esa.int/en/projects...
An improved downscaling method for the 25-km European Space Agency (ESA) Climate Change Initiative (CCI) SSM product was proposed to obtain daily seamless downscaled SSM series at a 1-km scale. The Moderate Resolution Imaging Spectroradiometer (MODIS) Terra daily land surface temperature (LST) ...
ESA CCI SM products have provided remotely-sensed surface soil moisture (SSM) content with the best spatial and temporal coverage thus far, although its output spatial resolution of 25 km is too coarse for many regional and local applications. The downscaling methodology presented in this paper imp...

The inherent biases of different long-term gridded surface soil moisture (SSM) products, unconstrained by the in situ observations, implies different spatio-temporal patterns. In this study, the Random Forest (RF) model was trained to pr... L Zhang,Y Zeng,R Zhuang,... - 《Remote Sensing》...

What are the impacts of the selected model representative soil depth and the meteorological forcing on the comparison between the satellite and model SSM? What are the strengths and weaknesses of a few (widely used) temporal comparison metrics? What is the potential of these metrics for future ...
SMMR, SSM/I, TMI, AMSR-E, WindSat, and AMSR-2 data were utilized for passive microwave products. These data were inverted, incorporating the LPRM v5 inversion model jointly developed by Vrije Universiteit Amsterdam and NASA. In addition, the data were integrated to produce passive microwave ...
