CoSMOS is an ESA airborne campaign to be performed in 2005 (April-May-June) in the frame of the SMOS (Soil moisture and ocean salinity) programme. The SMOS sensor, to be onboard a satellite, is a L-band radiometer, from which it will be possible to retrieve both the surface moisture of land surfaces and the surface salinity of the ocean. For the spring 2005 validation campaign, the aircraft will be the Convair 580 from Environment-Canada. The airborne instrumentation will include a L-band radiometer (TUD) fully polarimetric, and able to measure at two distinct incidence angles (nadir and 40°). Over the Toulouse area, the flight height will be 500 m for a ground resolution of 300-350 m. The frequency of flights will be about one every 3 days, i.e. 30 flights during the 3 month period. The specific objectives over the Toulouse region will be to:

test the assimilation of future SMOS data in near-operational conditions, in a data rich area (operational atmospheric measurements and soil moisture products at a resolution of 8 km will be available)
generalise the results of long term in situ measurements like those performed since 2003 at the SMOSREX site near Toulouse by Météo-France, CESBIO, ONERA and INRA
assess the use of the future SMOS data at the regional scale
complete the research effort on the L-band emission of forests started during EUROSTARSS (2001), a previous ESA campaign.

During the flights around Toulouse, the airplane will overpass several ground-based stations, installed on various landscapes, and on which meteorological as well as ground parameters (temperature and water) will be measured.
