Downscaling soil moisture

WebSoil moisture (SM) is an important element in the hydrologic cycle, especially influencing precipitation, infiltration, and runoff ( Hamlet et al., 2007 ). SM is thus useful for different applications such as meteorology ( Dirmeyer, 2000 ), climatology ( Douville, 2004 ), hydrology ( Chen et al., 2011) and agriculture ( Guérif and Duke, 2000 ). WebApr 18, 2013 · The foremost objective of this research is on the application of GLM, ANN and RVM for evaluating their downscaling capabilities of the SMOS soil moisture through the soil moisture deficit derived from Probability Distribution Model (PDM) over the Brue catchment, Southwest of England measured at the time closest to SMOS overpass.
