3 Rome 25 June 2009 Study area The area of interest covers the North-Eastern Mediterranean Sea including the Adriatic and upper parte of the Ionian sea (see Fig. 1). The Adriatic Sea is a body of water separating the Italian Peninsula from the Balkan Peninsula. It extends northwest from 40 to 45 45' N., with a n extreme length of about 770 km. The largest river in the North-Eastern Mediterranean Sea, in the Adriatic, is Po river and its mouth is a great source of detritus and nourishment affecting both the water quality parameter and the water circulation

4 Regional bio-optical optical algorithm: Development of Case2 water algorithms the coastal water of the North-Eastern Mediterranean Sea. The bio-optical algorithms define the optical properties of the main water compounds and connects them to the optical properties of the water body; the radiative transfer model links the optical properties of the water to the radiometric field. Their junction allows estimating radiometric quantity in relation to the abundance of water compounds and their properties of light absorption and scattering. The numerous coastal sea campaigns already permed by the proposing team (two oceanographic cruises are already scheduled in 2010) have allowed to spectrally characterize the optical properties of the coastal water in North-Eastern Mediterranean Sea.

5 Inversion technique applied products : Water compounds concentration maps obtained by inversion techniques of physical algorithms applied to airborne (MIVIS) and satellite (Hyperion) data. Chlorophyll, CDOM and TSS concentration maps plus RMS map obtained by MIVIS acquisition over the strait of Messina Water compound maps obtained by MIVIS (left) and Hyperion (top) acquisitions over the lagoon of Venice

6 Validation of OCM derived geophysical parameters Comparison of MODIS and OCM chlorophyll data using appropriate existing algorithms will be permed. The Potenza ground station will provide the MODIS products the investigated area by assuring reference values the OCM-2 retrieved water quality parameters CAL/VAL purposes of the algorithm results obtained from OCM-2 data. Inter-sensor Data comparison and data mergin MODIS surface temperature (SST), and the OCM-2 based inmation on the biological activities thorough the ocean colour will be used to analyse the Case2 frontal dynamics. COSMO-SkyMedn data, MODIS SST and OCM-2 retrieved bio-optical properties will be combined to analyse the river plumes and the limit of Case1-Case2 waters ROSA and X-band images (provided by the Cosmo Sky-Med constellation) will be deeply investigated in the Case of a financial support obtained by the Italian Space Agency (ASI).

7 Type of data products required (season(s), periodicity and number) OCM-2 2 images (Level 1C LAC) and geo-physical parameters (Level 2C LAC: chlorophyll concentration, total suspended matter, aerosol optical depth, diffuse attenuation coefficient) acquired weekly. Scatterometer wind data (Level 2B) acquired weekly.

9 Background experience Since 2000 the proposing research group (i.e. CNR-IMAA IMAA-Potenza,, CNR-IIA IIA-- Rome, CNR-ISMAR ISMAR-Venezia,, CRPSM of the University of Rome La Sapienza) ) has been involved in many international and national scientific projects on the characterization of the sea/coastal water through Earth Observation technologies. In particular the scientific group has been developed activities relative to quantitative evaluation of physical models retrieving eving bio-optical optical parameters correlated to the waters quality (specifically Case-I I and Case-II water, oligotrofic and mesotrofic waters). Moreover, the proposing group is studying the spectral properties of the main submerged vegetation species (i.e. algae and macrophites) ) in order to refine the species detection and to derive indexes to stress precondition of the abnormal algae blooms (important in northern n Adriatic sea the socio-economic aspect of the coast line).
