Estimation of root zone soil moisture and surface fluxes partitioning using near surface soil moisture measurements

Journal of Hydrology, 2002
Abstract We examine the feasibility of retrieving root zone soil moisture and partitioning of surface fluxes through a model inversion technique using surface measurements. Using a four-layer land surface model and observed datasets from Field Experiment (FIFE) 1987, we show that the sensitivities of surface soil moisture to deeper layer soil ...

On the estimation of soil moisture profile and surface fluxes partitioning from sequential assimilation of surface layer soil moisture

Journal of Hydrology, 1999
Abstract Recent studies have shown that a variety of remote sensing techniques may be used for the estimation of soil moisture over large areas. The shallow moisture sensing depth of passive microwave measurements, however, limits the use of remotely sensed soil moisture for many land–atmosphere interaction studies.

Effects of Near-Surface Soil Moisture on GPS SNR Data: Development of a Retrieval Algorithm for Soil Moisture

IEEE Transactions on Geoscience and Remote Sensing, 2014
Global Positioning System (GPS) multipath signals can be used to infer volumetric soil moisture around a GPS antenna. While most GPS users concentrate on the signal that travels directly from the satellite to the antenna, the signal that is reflected by nearby surfaces contains information about the environment surrounding the antenna. The interference

The Seasonal Cycle of Surface Soil Moisture

Journal of Climate, 2022
Abstract The seasonal cycle contributes substantially to soil moisture temporal variability in many parts of the world, with important implications for seasonal forecasting relevant to agriculture and the health of humans and ecosystems. There is considerable spatial variability in the seasonal cycle of soil moisture, yet a lack of global observations ...
