Remotely sensed surface data over the ocean constitute an independent and quasi-synoptic source with which in situ estimates, such as ship, buoy and coastal/island station data or marine-atmospheric modelling outputs can be complemented and compared. We focus on the Mediterranean Sea, where all the water masses are formed at the surface via recurring extreme air-sea interaction events, thereby rendering necessary the monitoring of the air-sea interaction parameters for the understanding of the variability in the characteristics of the water mass characteristics and circulation. The combined use of passive microwave (SSM/I) and thermal (AVHRR) satellite data has permitted to develop algorithms to obtain specific humidity q, air temperature Taand wind intensity U. We obtained these from the literature and applied them to the Mediterranean SSM/I data, with the final scope of monitoring its energy and water budgets. The present preliminary validation effort is made against the meteorological data relative to a number of oceanographic cruises carded out on board R/V Urania of the Italian National Research Council (CNR), a data set coming from a moored buoy managed by the Istituto di Automazione Navale (IAN-CNR) and the ECMWF and MIAO model results.
