| Objective | Collecting the most in situ information possible in order to interpret measurements from the CAROLS (Cooperative Airborne Radiometer for Ocean and Land Studies) and from the radiometer aboard the SMOS (Soil Moisture and Ocean Salinity) satellite from Brest to the Gironde estuary via the 'Gascogne' buoy. This should lead to improved algorithms to reconstruct the sea surface salinity (SSS) based on L-band radiometric measurements. Since late 2007, CAROLS has been flying in various configurations, optionally associated with the STORM ocean surface radar from LATMOS, on the French scientific community's ATR42 research aircraft operated by the SAFIRE joint service unit (Météo-France/CNRS). Numerous aspects concerning the measurement theory or parasite contaminations can thus be explored and assessed, both on the ocean and on continents. The cruises in September 2007 and November 2008 enabled the aeronautical certification of airborne instruments on the ATR42, validation of the quality of data measured and of calibration protocols and analysis of disturbing effects related to radiofrequency interference. The cruise made in Spring 2009 made it possible to collect a broad base of CAROLS data, accompanied by field measurements to develop and improve inversion algorithms to estimate soil moisture and ocean salinity. The 2010 cruises aimed to enrich the CAROLS database with measurements taken simultaneously with satellite passes. In May 2010, CAROLS radiometer flew with its two antennas which could provide measurements with two angles of incidence; during this cruise in November, it flew with only one antenna, but was accompanied by the STORM backscattering meter to measure the wind. The cruise in the field measured SSS, SST and atmospheric parameters (wind) under the aircraft's track. |
