Objective Collecting 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 taken of the Gironde estuary at the 'Gascogne' buoy and on a leg at 44N. 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 first two cruises took place in September 2007 and November 2008. They 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 radio-frequency 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 cruise aimed to enrich the CAROLS database with simultaneous measurements at satellite passes (measuring SSS, SST and atmospheric parameters (especially wind) under the aircraft's track. The flights were coordinated for the first time with the satellite's passes - flights on 6 May in evening - 8 May in morning - 11 May in evening and 18 May, after the 10 May flight was cancelled for requisitioning. Deployment of autonomous sensors for monitoring during flyover on 18 May.
