What is SMOS?
ESA's Soil Moisture Ocean Salinity (SMOS) Earth Explorer mission is a radio telescope in orbit, but pointing back to Earth not space. It's Microwave Imaging Radiometer using Aperture Synthesis (MIRAS) radiometer picks up faint microwave emissions from Earth's surface to map levels of land soil moisture and ocean salinity.
These are the key geophysical parameters, soil moisture for hydrology studies and salinity for enhanced understanding of ocean circulation, both vital for climate change models.

Successful deployment of the new SMOS level 1 and level 2 algorithm baseline V620 in the operational processing
07 May 2015
ESA would like to inform SMOS data users about the successful deployment of the new level 1 processor version 620, the new level 2 sea surface salinity processor version 622 and the new level 2 soil moisture processor version 620 in the operational ground segment.
ESA would like to inform the SMOS data users about the availability of a new level 1 reprocessed dataset covering the entire period of the SMOS mission from January 2010 to 5 May 2015 (a catch-up reprocessing for the period from February 2015 to May 2015 will be provided in the coming weeks). The products have been generated with the new level 1 processor version 620 recently deployed in the operational ground segment.
ESA would like to inform SMOS data users that next week a new level 1 and level 2 algorithm baseline (V620) will be deployed in the operational ground segment. For this reason the production of the SMOS level 1, level 2 products will be suspended on 05 May 2015. It is planned to resume the production and the dissemination of the level 1, level 2 products on 07 May 2015 in the evening.
