1. ECOOP – WP2.3 Ensure proper and maximum real time delivery of remote sensing data Participants: CNR, ENEA, DMI, IFREMER, AZTI-Tecnalia, NERC, CLS, PdE, NUIC, DNSC

2. Objectives • integrate existing satellite observing systems • coordinate access to Earth Observation (EO) products taking full advantage of existing national and European resources • ensure advanced satellite products for monitoring and assimilation into ECOOP models during TOP Links with other WPs • WP3: satellite products based upon the results of the R&D activity • WP8: ECOOP information management

3. First year activities Design of the RT and NRT data satellite acquisition and delivery system for the TOP phase  D2.3.1.1 (CNR, Ifremer, CLS, DMI) Activities: • analysis of current satellite systems/products • analysis of WP3 outcomes and planned activities for the next 6 months • analysis of the in situ data required to produce advanced R/S products • design of the RS observing system for TOP: data input, products, format, delivery systems

4. Satellite products The new Satellite products to be assimilated by ECOOP models include: • SST merged R/S - in situ products (Gulf of Biscay, Adriatic and Baltic Seas) • Altimetry merged R/S with tide gauges and mean dynamic topography (Gulf of Biscay and Black Sea) • Ocean Colour merged R/S - in situ products (Gulf of Biscay and Adriatic Sea) ECOOP-WP3

5. Sea Surface Temperature • During TOP, specific ECOOP SST data will be produced by EuroGOOS sub-region SST processing systems after introducing the improvements resulting from WP3 • SST data input: ECOOP-WP3

6. L2P data products provide satellite SST observations together with a measure of uncertainty for each observation • L2P data are written in a common netCDF format, following CF 1.0 conventions

7. ECOOP-WP3

8. SST: Gulf of Biscay IFREMER Present: IBIROOS area is covered by the multi-sensor L4 SST products computed by Ifremer using data from both infra-red and micro-wave radiometers Daily global SST with a resolution of 0.1°res. NRT SST are produced since October 2007. ECOOP Improvements The ODYSSEA chain will be used and tuned to provide daily SST fields at a higher resolution (0.02° res.) over the IBIROOS area. Improvements in the intercalibration using in situ data Including all coastal stations Data format : Netcfd, complying to CF-1.0 convention and GHRSST format Delivery system ftp and OpenDAP

9. SST: Baltic Sea DMI • Present: • L2P data corrected from skin to subskin • single sensor error bias applied to all sensors • relevant satellite observations used as input for the Baltic Sea L4 processing system (DMI) at 0.03° res. ECOOP Imprevements Merged multi-sensor L4 at 0.03° res. Adjustment of all satellite observations to the most accurate sensor (AATSR) Include near-real time MARNET buoy observations in the L4 analysis, if required. Data format : Netcfd, complying to CF-1.0 convention and GHRSST format Delivery system ftp and OpenDAP

10. SST: Adriatic CNR Present: Adriatic Sea is covered by the several SST products provided by the CNR Daily images at 1km res. from AVHRR and MODIS Daily SST data over the Adriatic model grid (AREG), 5km NRT Mediterranean multi-sensor OISST (L4) at 1/16° res. NRT SST Adriatic products available since October 2002, Mediterranean multi-sensor L4 since 2006.
