Investigating Soil Moisture Dynamics in Australian Arid Zones: Murrumbidgee Airborne Experiments
This study focuses on airborne and ground-based experiments conducted in the Australian Arid Zone, particularly the Murrumbidgee River Catchment, to validate SMOS satellite observations. Key objectives include the preliminary identification of reference sites, actual calibration/validation experiments, and model validation efforts. The work involved high-resolution (50m) and low-resolution (1000m) measurements of surface and profile soil moisture, temperature, and roughness across various arid regions, including the Wirrangula Hills, Simpson Desert, and Lake Eyre.
