- 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 aggregated 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.
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_CLF3ax_startdate_enddate_vvv_ccc_7
- clas : File class (OPER : operational mode, REXX : reprocessing xx)
- a : 3 for 3 days, D for 10 days, M for 1 month
- 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)
