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 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. Only descending orbits are processed.

Products from operational (OPER) processing are available since 02/2020.

The scientific dataset from 2010 to the end of january 2020 is currently available at ftp://ext-catds-cecsm:catds2010@ftp.ifremer.fr/Land_products/L4_Root_Zone_Soil_Moisture/MIR_CLF4RD/

File naming :

SM_clas_MIR_CLF4RD_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)
