ECOOP WP7, led by Pierre Yves LE TRAON, aims to improve the use of existing remote sensing and in situ data for coastal and regional seas, as well as develop synergies between observing networks. The focus is on validation, assimilation or use of data for model or forcing validation. Potential partners include CLS, LEGOS, ICM, IFREMER, BOOST, CNR, INGV, UKMO, DMI, Met no, NERSC, ESEAS, MERSEA and MFS consortiums.

These data sets will be either assimilated or used for model or forcing validation. Potential partners : CLS, LEGOS, ICM, IFREMER, BOOST, CNR, INGV, UKMO, DMI, Met.no, NERSC, ESEAS, MERSEA and MFS consortiums. We should first agree, however, on work content, regional areas and then look for partners.

WP7.2 Mean sea level in coastal/regional seas to reference altimeter data WP7.2 Mean sea level in coastal/regional seas to reference altimeter data Because of geoid uncertainties, altimetry provides only sea level anomaly data. GOCE (2006) will provide very accurate geoid models that will have a major impact on the use of altimetry in regional seas (absolute sea level). Because of geoid uncertainties, altimetry provides only sea level anomaly data. GOCE (2006) will provide very accurate geoid models that will have a major impact on the use of altimetry in regional seas (absolute sea level). Improved high resolution mean dynamic topographies should thus be developed from GOCE and altimeter data for regional/coastal seas + analyze the impact of MDT on altimeter data use and assimilation in regional/coastal models.

7. ECOOP Meeting ECOOP Meeting March 14-21, 2005 March 14-21, 2005 Issues for WP7 Issues for WP7 Quality of assimilated regional/coastal products will (highly) depend on the quality of input data. Need R&D on R/S-in-situ data (WP7). Focus the WP7 (R&D) work on specific regions ? Issues for other WPs in ECOOP Need efficient data processing and data distribution systems with long- term commitment. ECOOP must rely and establish strong links with MERSEA thematic centers/portals (this is critical for the overall GMES architecture) Need to establish links between WP7 and production WPs for in-situ and remote sensing data (transfer of R&D results). Work should be planned in R&D assimilation to assess the value of improved remote sensing/in-situ products. + organize real time access to European tide gauge
