SMOS : the "Global water cycle mission"
Soil Moisture and Ocean Salinity
SMOS (Soil Moisture and Ocean Salinity) mission is a joint ESA / CNES / CDTI Earth Observation program. The SMOS mission proposed by CESBIO has been selected as the 2nd Earth Explorer Opportunity Mission. The SMOS satellite was launched the November 2, 2009.
The objective of the SMOS mission is to provide Soil Moisture (SM) and Ocean Salinity (OS) maps. Both SM and OS are key variables in climate monitoring, surface / vegetation / atmosphere transfers, and ocean / atmosphere cycles.
The SMOS Satellite Control Centre will be adapted by CNES from generic PROTEUS ground segment and installed in Toulouse within the CNES premises. A SMOS Mission Centre dedicated to level 1 and 2 products, is being developed and located in the ESA / Villafranca centre. A specific Data Processing Centre dedicated to level 3 and 4 products is being developed by CNES (CATDS).

The Centre Aval de Traitement des Données SMOS (CATDS), developped by the CNES in collaboration with the CESBIO and IFREMER, is dedicated to :
The CATDS is made up of 3 centers :
- Data Production Center (CPDC), hosted by IFREMER Brest
- Soil Moisture Expertise Center (CEC-SM), hosted by CESBIO Toulouse
- Ocean Salinity Expertise Center (CEC-OS), co-hosted by IFREMER Brest and LOCEAN Paris
