Satellite Soil Moisture and Its Applications

摘要

With satellite soil moisture (SM) retrievals becoming widely and continuously available, it is desirable to use the remote sensing SM data to enhance the accuracy of weather forecast and flooding prediction, improve natural disasters (e.g., drought, dust storm, wild fire, and flood) monitoring, and identify the role of SM in climate change. To promote the application of SM retrievals, downscaling satellite SM data from coarser to finer resolution and combining individual SM retrievals to generate a blended SM product, as well as optimizing bias-correction approach in the land data assimilation system have been reported in recent researches.
