This product is an aggregation of daily maps of soil moisture, over a 3 day moving window, a decade or a month. Ascending and descending orbits are processed separately.

This product is a synthesis product of brightness temperatures for L-Band frequency. It includes all brightness temperatures acquired that very day by the SMOS satellite operating in full pol mode. Values correspond to those at the top of the atmosphere level, transformed to the ground polarisation reference frame, binned and averaged into fixed incidence angle classes. This product is available on each of the EASE2 grid projections (cylindrical and polar).

This product is the daily product of soil moisture. The retrievals are based on a multi-orbit retrieval algorithm. Ascending and descending orbits are processed separately.

This product is the daily product of soil moisture, and contains filtered data. The retrievals are based on a multi-orbit retrieval algorithm. A detection of freeze and snow is performed and added to the flags. Ascending and descending orbits are processed separately.

This product is radio frequency interference (RFI) probability for each angle bin computed daily and based on a monthly moving window average. Ascending and descending orbits are processed separately, and only in full polarization. ** This product is no longer available, see below **

This product contains average 10 days & monthly salinity field corrected from land-sea contamination and latitudinal bias, based on L2Q products, mixing ascending and descending orbits.

This product contains daily salinity fields from a 9 days temporal gaussian average, corrected from land-sea contamination and latitudinal bias, based on L2Q products, mixing ascending and descending orbits.

This product is a daily product of root zone soil moisture representative of the 0-1 m depth of the soil. The base products, for all the CATDS-PDC (Centre Aval de Traitement des Données SMOS - Production & Dissemination Center) processing chains, are the SMOS L1B products from ESA (European Space Agency). The L4SM RZSM is the daily product of root zone soil moisture (m3/m3) representative of the 0-1 m depth of the soil. The product contains also a quality index taking into account the presence of Radio Frequency Interference (RFI), low quality of retrieval of the input surface soil moisture, and a high fraction of non-nominal surfaces. Products from reprocessing RE07 are available for the period 01/2010 - 05/2021. Products from operational (OPER) processing are available since 06/2021. Reprocessed products and operational products are derived using the same algorithm and configuration, hence ensuring the temporal continuity.

This product contains daily salinity fields from a 9 days temporal gaussian average, corrected from land-sea contamination and latitudinal bias, based on L2Q products, mixing ascending and descending orbits. The base products, for all the CATDS-PDC (Centre Aval de Traitement des Données SMOS - Production & Dissemination Center) processing chains, are the SMOS L1B products from ESA (European Space Agency). From these, brightness temperatures at various incidence angles are reconstructed. The Sea Surface Salinity (SSS) are retrieved from multi-angular brightness temperatures through a maximum likehood Bayesian approach in which measured Tb and Tb simulated using a forward direct model are compared (see Zine et al. 2008 for a general description of the retrieval method, and pro_con table for a summary of the similarities/differences with respect to ESA level 2 ocean salinity processing). Products from reprocessing RE07 are available for the period 02/2010 - 05/2021. Products from operational (OPER) processing are available since 06/2021. Reprocessed products and operational products are derived using the same algorithm and configuration, hence ensuring the temporal continuity.

This product contains average 10 days & monthly salinity field based on L2P products, mixing ascending and descending orbits. ** This product is no longer available, see below **
