The European Space Agency’s Soil Moisture and Ocean Salinity (SMOS) mission was launched in November of 2009 in order to measure and map soil moisture levels over land and sea surface salinity over oceans (more detail: Mapping the Salinity of the Ocean). The SMOS Barcelona Expert Center recently released products available for downloading relating to Sea Surface Salinity for the North Atlantic Ocean and the Mediterranean Sea. These products can be dowloaded via the center’s THREDDS server (before downloading, a free registration is required).
The datasets were produced using a combination of debiased non-Bayesian retrieval, DINEOF (Data Interpolating Empirical Orthogonal Functions) and multifractal fusion. The methodology and analysis of the products’ accuracy are outlined in this paper:
