1 The development and generation of the long term Mediterranean SSR products Rosalia Santoleri, Gianluca Volpe, Cristina Tronconi, Roberto Sciarra Istituto di Scienze dellAtmosfera e del Clima – sezione di Roma Via del Fosso del Cavaliere, 100 – 00133 Roma r.santoleri@isac.cnr.it; c.tronconi@isac.cnr.it; g.volpe@isac.cnr.it; r.sciarra@isac.cnr.it;

2 The generation and development of the long term Mediterranean SSR products The aims are: 1.to identify and develop of an optimal algorithm for the Mediterranean sea to produce high quality ocean colour datasets for the region. 2.to provide an accurate and consistent stream of ocean colour data at a resolution and format compatible with operational forecasting of the Marine Environment. The SeaWiFS reanalysis from 1997 to 2004

3 Outline SeaWiFS OC bio-optical algorithm Satellite matchup –Chlorophyll –Rrs (MBR) Histograms to show the blue-green shift MERIS and MODIS sensors –Chlorophyll –Rrs (MBR) SeaWiFS reanalyses of MED dataset as distributed by MERSEA Regional satellite products impact on PP –Global model –Regional model

4 In situ chlorophyll-a data: 1144 chlorophyll profiles for satellite data validation Mediterranean Ocean Color CAL/VAL DATA SETS 28 Mediterranean cruises: from 1997 up to now were organized by ISAC in the framework of Italian National Projects + 2 permanent stations Bio-optical measurements: 155 chl/opt measurements to define the Mediterranean regional algorithm (red points) Optical measurements: 938 SIMBADA for Rrs validation (blue points)

5 SeaWiFS OC bio-optical algorithm MedOC4 bio-optical algorithm Chlorophyll a [mg m -3 ] 0.010.1110 10 1 Maximum Band Ratio

6 Chlorophyll a [mg m -3 ] 0.010.1110 Satellite matchup: Chlorophyll

7 Satellite matchup: Remote Sensing Reflectance
