Towards harmonious downscaled soil moisture maps from the SMAP and SMOS satellites

Accurate soil moisture maps at spatial resolutions between 1 to 10 km are required for regional and local earth system applications. This thesis explores the most appropriate downscaling methodology(ies) for the low-resolution soil moisture products of the Soil Moisture Active Passive (SMAP) and the Soil Moisture and Ocean Salinity (SMOS) satellite missions for soil moisture mapping at 1 to 10 km. Combinations of soil moisture retrievals from different downscaling algorithms is also tested as a step towards harmonious multi-sensor soil moisture retrievals at 1-10 km for a typical Australian landscape.
