The Campaign for Validating the Operation of SMOS (coSMOS) was designed to acquire SMOS-like data so that the algorithms were fine-tuned and properly validated before the launch of SMOS mission in 2007.

The campaign started in mid-April 2005 and took place in a number of places in France and Spain, as well as over the Atlantic Ocean. The objective was to take measurements of moisture in the soil and salinity in the surface-waters of the ocean using an L-band radiometer developed specifically for the campaign by the Technical University of Denmark. The radiometer, which comprised of two large antennae so that the ground could be viewed under different geometries simultaneously, was mounted in an aircraft and flown over designated target areas.


What was the outcome of CoSMOS 2005, 2007, 2008, 2010?

In conclusion to this campaign, consistently successful missions delivered good data quality with no loss of data!

Inspection of the third and fourth Stokes parameters have a promising potential when it comes to detecting RFI in the EMIRAD and SMOS contexts.
