The main goal of Barcelona Expert Center (BEC) is to generate higher added-value products of interest for a broad range of users. With this aim we offer the following variables:

Ocean variables

Sea Surface Salinity

These products have been generated from SMOS Level 1B products provided by ESA using a new methodological approach to cope with land and RFI contamination. This methodology is known as Debiased non-Bayesian and it is described at [Olmedo2017]
