More Information
Summary:Knowledge of the temporal dynamics and spatial variability of soil moisture is crucial in understanding many environmental processes and their impacts on plant fertility, crop yields, droughts, or exposure to flood hazards. The Soil Moisture Active Passive (SMAP) satellite was launched on 31 January 2015 by the National Aeronautics and Space Administration (NASA) to provide SSM using brightness temperature through its active (radar, 3 km) and passive (radiometer, 36 km) sensors at an intermediate resolution of 9 km. [...]we utilized these advancements to further postprocess the downscaled soil moisture dataset at 1-km spatial resolution and provide a more accurate and reliable product. According to the U.S. Department of Agriculture National Agricultural Statistical Service (USDA NASS), the rice farmlands are flooded and seeded each year from late April through May.
