Three years ago, the BEC team introduced a new method for the retrieval of SSS from SMOS data: the debiased non-Bayesian approach. The method was first used to derive the first maps of SMOS SSS in the Mediterranean.
After three years, we have extensively validated the method, first in the Mediterranean, then in the Arctic and finally globally.The debiased non-Bayesian approach is now a consolidated technique, and reportedly the one providing the best estimates of SSS using SMOS data in any area of the global ocean.
In the next months, we plan to introduce new improvements. Very soon, we are going to serve an extended series of improved Arctic SSS maps. And in some months from now, we will deliver the first SSS maps ever in a very challenging area: the Baltic Sea. And this is only the beginning: we plan to ensure an almost operational generation of all debiased non-Bayesian SSS maps (that is, the maps will be generated with a short delay, a few weeks at most).
