This product is no longer available. Instead, we recommend to use the product CATDS-PDC L3OS 3Q mixed - Debiased average 10 days & monthly salinity field product from SMOS satellite, mixed orbits ( https://doi.org/10.12770/0f02fc28-cb86-4c44-89f3-ee7df6177e7b). However, if the L3OS 3Q mixed product doesn't fit your need, and you really need access to the L3OS 3Q separated product, please send us a message with the appropriate justification at support@catds.fr .
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).
The L3OS 3Q mixed product contains average 10 days & monthly salinity field corrected from land-sea contamination and latitudinal bias, based on L2Q products, at 4 spatial resolutions (25km, 50km, 100km, 200km), ascending and descending orbits being processed separately.
Products from reprocessing RE05 are available for the period 01/2010 - 03/2017. Products from operational (OPER) processing are available since 04/2017. Reprocessed products and operational products are derived using the same algorithm and configuration, hence ensuring the temporal continuity.
Note that links are only provided for the 25km spatial resolutions products. Other resolutions can be accessed by changing the product name (see below)
File naming :
SM_clas_MIR_CSQ3rx_startdate_enddate_vvv_ccc_7
- clas : File class (OPER : operational mode, REXX : reprocessing xx)
- r : A for 25km, B for 50km, C for 100km, D for 200km
- x : A for ascending orbit, D for descending orbit
- startdate : sensing start date/time of the data (format yyyymmddThhmiss)
- enddate : sensing end date/time of the data (format yyyymmddThhmiss)
- vvv : version number of the processor generating the product
- ccc : file counter
File format :
In each archive file (.tgz extension), there are two files
- A Header file (.HDR), which is a text file, in XML Earth Explorer Header format
- A Data file (.DBL.nc), which is a netcdf file, format variant 2 (netcdf 3 with 64 bits offset option)
