Description

Multi Observation Global Ocean Sea Surface Salinity and Sea Surface Density is an oceanographic product that provides daily, global, and gap-free Level-4 (L4) analyses of Sea Surface Salinity (SSS) and Sea Surface Density (SSD) at a high resolution of 1/8 degree. This product is generated by blending observations from multiple satellite missions (like SMOS and SMAP) with in-situ measurements (such as those from Argo floats and TSGs) using a sophisticated multivariate optimal interpolation algorithm, thereby creating a long and consistent time series that includes both historical (reprocessed) data and near-real-time updates. By delivering these climate variables, the dataset is useful for monitoring the global water cycle, studying changes in ocean circulation driven by density variations, and serving as an input for climate modeling and ocean forecasting systems.

This dataset provides the Multi-Year Reprocessed version of the daily, global, Level-4 analysis for Sea Surface Salinity (SSS) and Sea Surface Density (SSD).
