ResumenA new set of surface density products at 1/4º of resolution and global scale have been developed at BEC. Those products are derived from the 3-day, 9-day, monthly and seasonal L3 SSS SMOS products, combined with Reynolds SST maps resampled at equivalent spatial and temporal resolutions. The density maps are produced using the new equation of state for seawater, the Thermodynamic Equation of Seawater - 2010 (TEOS-10), which replaces the EOS-80 as the official description of seawater and ice properties. Assessing the quality of the density products is not easy and requires an examination of connection between surface density and ocean media fulfil lambertian conditions for the engaged dynamics. According to theory, horizontal velocities can be diagnosed from density anomalies under the appropriate environmental conditions. Hence, to assess the quality of our density products, we have derived surface velocities from density products using the Surface Quasi-Geostrophic (SQG) equations and compared the results with independent velocity estimations. To test the feasibility of this approach, we have focused on those density products that contain mesoscale features and SQG equations can be applied. Results have been compared with velocities derived from the altimeters on Jason-1/2 platforms
