In a first part we describe the scientific objectives of SOFIA (Surface of the Ocean Fluxes and Interactions with the Atmosphere) and the intrumentation used during the experiment. We also present the scientific objectives directly related to ASTEX concerning the structure of boundary layer clouds.
In a second part, we analyze the main observations of SOFIA using 1) shipborne and buoys intrumentation and 2) constant level balloons and the french atmospheric aircraft. The data availability and data quality is considered.
In a third part are discussed results obtained during two selected days June 8 and June 17. June 8 concerns air-sea interaction investigations and we compare different methods of fluxes estimate. New methods to infer fluxes are proposed taking into account of mean meteorological parameters in the mixed layer using for example tethered balloon and aircraft data as well as constant level balloon informations. June 17 is more dedicated to cloud structure analysis with Polder and the airborne Lidar (Leandre).
In the conclusions, we demonstrate the different research undertaken, we show
the need of data and cooperation and suggest several scenarios of investigation
which could be useful for several investigators.
