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.

The SMOS nominal production has resumed after the successful deployment of the new L2SM v650 processor.
15 November 2017
Due to the operational deployment of the new L2SM v650 processor, SMOS nominal production will be delayed on 15 November 2017. Production is expected to be fully reestablished on 16 November.
ESA would like to inform the SMOS data users that the full reprocessed SMOS level 2 sea surface salinity dataset is now available on the SMOS data dissemination service. Following the reprocessing that finished in May 2017 a "gap-filling" reprocessing was performed to align to the operational product start.

03 November 2017
A new, long-term and global dataset of soil moisture measurements from space has been released to help us better understand the water cycle and climate, monitor agriculture and manage our water resources.

Satellites such as Europe's Copernicus Sentinel missions and ESA's SMOS and the upcoming Florescence Explorer, FLEX, provide a wealth of information about growing conditions and crop health that can be used to improve agricultural efficiency.
In-situ DOMEX-3 measurements for 2016 are now available for Cal/Val users along with the yearly campaign report. The measurements were acquired over the Antarctic plateau close to the Concordia base by tower based L-Band radiometer and by on-ground sensors for snow properties.

Satellites are helping to predict favourable conditions for desert locusts to swarm, which poses a threat to agricultural production and, subsequently, livelihoods and food security.
