This product contains average 10 days & monthly salinity field based on L2P products, ascending and descending orbits being processed separately. ** This product is no longer available, see below **
-
This product is an aggregation of daily maps of dielectric constant and its associated parameters over a 3 day moving window. The whole Earth's surface is covered in this 3-day product. Ascending and descending orbits are processed separately.
-
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.
-
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.
-
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.
-
Raw seismic reflexion data collected on board of the French oceanographic fleet managed by IFREMER and archived at SISMER.
-
Reflectivity measurements of the multibeam echosounders of the French Research Vessels
-
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 **
-
Raw underway marine gravity data from the French civil Research vessels and archived at SISMER (IFREMER)
-
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.
