On the spatial scaling of soil moisture
Web17 de jun. de 2016 · We have developed a spatial upscaling method for SMC that enables the direct combination of in situ measurements and remotely sensed data. The approach is based on the fact that spatial soil moisture patterns are related to ancillary features like topography, land cover, and soil type.
