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).

Position théorique du trait de côte (pied de dune) estimée en 2020, sans les ouvrages (sauf ouvrages majeurs du Verdon, de l'Adour et de l'Artha à St-Jean-de-Luz), uniquement sur la côte sableuse. (métadonnée en cours)

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 is an intermediate product, that provides, in daily files, SSS with qualification flags (associated confidence classes) which allow selecting valid data before averaging. Ascending and descending orbits are processed separately ** This product is no longer available, see below **

This product is a daily product of root zone soil moisture representative of the 0-1 m depth of the soil.

This product contains weekly salinity field, based on SMOS satellite data, and ISAS (In-Situ Analysis System). The L4OS SMOS-OI product contains global Level 4 analyses of the of the Sea Surface Salinity (SSS), Sea Surface Density (SSD) and Sea Surface Spiciness (SSSp), along with Sea Surface Absolute Salinity (SSA), Conservative Temperature (SCT), surface thermal expansion coefficient (alpha) and haline contraction coefficient (beta). The SSS product is obtained using an optimal interpolation (OI) algorithm, that combines ISAS in situ SSS OI analyses and Soil Moisture Ocean Salinity (SMOS) satellite image to reduce large scale and temporally varying bias. The SSS L4 product outcome is then combined with satellite SST products to compute thermodynamic sea water parameters using TEOS-10 (Kolodziejczyk et al., 2021). Products from reprocessing RE07 are available for the period 01/2011 - 05/2021. Products from operational (OPER) processing are available since 06/2021.

Spatial distribution for nutrients data (silicate, nitrate, nitrite, ammonium and phosphate) for all maritime regions in the English Channel and North Sea, the Celtic Seas and the Bay of Biscay. The temporal extent of the data is from 1930 to 2010, most being between 1974 and 2007 with a peak in 1999.

Spatial distribution of all oxygen data in degrees integrated vertically and horizontally for all sub-regions of the English Channel, the North Sea, the Celtic Seas and the Bay of Biscay.
