- 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.
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_CLF4Rx_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)
