Root Zone Soil Moisture Retrieval Using Streamflow and Surface Moisture Data Assimilation in Nested Catchments
Correct knowledge of soil moisture is important for improving the prediction of coupled land surface atmosphere interactions. This is due to the control that soil moisture exerts on the latent and sensible heat flux transfer between the land surface and atmosphere. Because of this strong dependence on moisture availability, improved atmospheric prediction requires correct initialisation of soil...
متن کاملEstimating Surface Soil Moisture Using Radarsat-2
Extremes in soil moisture, either too much or too little, present a significant risk to agricultural productivity. Managing and mitigating risk requires information and knowledge to assess risk potential, implement risk reduction strategies and deliver responses to this risk. Synthetic aperture radars (SARs) are sensitive to the dielectric properties of soils and are thus well suited to provide...
متن کاملEstimating profile soil moisture and groundwater variations using GRACE and Oklahoma Mesonet soil moisture data
[1] In this study we estimate a time series of regional groundwater anomalies by combining terrestrial water storage estimates from the Gravity Recovery and Climate Experiment (GRACE) satellite mission with in situ soil moisture observations from the Oklahoma Mesonet. Using supplementary data from the Department of Energy’s Atmospheric Radiation Measurement (DOE ARM) network, we develop an empi...
