WebMar 21, 2024 · Soil moisture based on microwave remote sensing has been frequently used for analyzing global-scale evapotranspiration regime transitions. However, microwave signals are mainly sensitive to surface soil moisture ( θ s ), which is not directly a sampling of root water uptake from the deeper soil profile. WebAug 15, 2024 · We use an SSM-based drydown detection methodology and an exponential model to estimate the drydown time scale. The errors generated by the SF and by using SSM instead of precipitation to define the start of the drydown period are examined using a synthetic soil moisture model.
