SMOS brings Mediterranean salinity into focus
11 May 2017
ESA's SMOS mission maps variations in soil moisture and salt in the surface waters of the open oceans. When the satellite was designed, it was not envisaged that it would be able to measure salinity in smaller seas like the Mediterranean, but SMOS has again surpassed expectations.
The satellite carries a microwave instrument to capture images of ‘brightness temperature', which correspond to microwave radiation emitted from Earth's surface and can be related to soil moisture and ocean salinity.
