SST, cloud classification and surface irradiances derived from operational satellite data during SOFIA/ASTEX and SEMAPHORE
- Meteo-France/SCEM/Centre de Meteorologie Spatiale, Lannion (France)
SOFIA is the French component of ASTEX which was organized in the Azores region in June 1992. The scientific objectives of SOFIA during ASTEX were the study of energy transfer between the sea surface and the atmospheric boundary layer at various scales. SEMAPHORE was organized in the same region in October and November 1993 and was centered on the study of mesoscale ocean circulation and air/sea interactions. During those experiments, the Centre de Meteorologie Spatiale produced in real time satellite estimates of Sea Surface Temperature (SST), cloud type, surface solar and longwave irradiance fields over the area (27N-40N, 15W-30W). This presentation will review briefly the methods which have been used to calculate these parameters. During both campaigns, in situ measurements were made by buoys (SST) and aboard the IFREMER ship Suroit (SST, surface solar and longwave irradiance). The results of the comparison of the calculations with the in situ measurements will also be presented.
