CATDS-PDC L3SM Filtered - 1 day global map of soil moisture values from SMOS satellite
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.

- Statement

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 - https://doi.org/10.57780/SM1-e20cf57 - from ESA (European Space Agency).
The L3SM filtered 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. The aggregated products are generated from this fundamental product.
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.
File naming :
SM_clas_MIR_CLF31x_startdate_enddate_vvv_ccc_7
- clas : File class (OPER : operational mode, REXX : reprocessing xx)
- 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)
