It provides access to integrated datasets of core parameters for initialization, forcing, assimilation and validation of ocean numerical models which are used for forecasting, analysis and re-analysis of ocean physical and biogeochemical conditions. The in-situ TAC comprises a global in-situ centre and 6 regional in-situ centres (one for each EuroGOOS ROOSs). The focus of the CMEMS in-situ TAC is on parameters that are presently necessary for Copernicus Monitoring and Forecasting Centres namely temperature, salinity, sea level, current, waves, chlorophyll / fluorescence, oxygen and nutrients. The initial focus has been on observations from autonomous observatories at sea (e.g. floats, buoys, gliders, ferrybox, drifters, and ships of opportunity). The second objective was to integrate products over the past 25 to 50 years for re-analysis purposes... Gathering data from outsider organisations requires strong mutual agreements. Integrating data into ONE data base requires strong format standard definition and quality control procedures. The complexity of handling in situ observation depends not only on the wide range of sensors that have been used to acquire them but, in addition to that, the different operational behaviour of the platforms (i.e vessels allow on board human supervision, while the supervision of others should be put off until recovering or message/ping reception)° CMEMS CMEMS INSTAC cmems-service@ifremer.fr author CMEMS cmems-service@ifremer.fr publisher https://sextant.ifremer.fr/geonetwork/srv/api/records/c457e612-3e6a-4811-ae70-5ae48f940223/attachments/cmems_insitu.png /Human Activities/Ocean Observation Network Thèmes Sextant 2017-09-22 publication geonetwork.thesaurus.local.theme.sextant-theme Environmental monitoring facilities GEMET - INSPIRE themes, version 1.0 2009-09-22 publication geonetwork.thesaurus.external.theme.httpinspireeceuropaeutheme-theme Monitoring Integrators AtlantOS Element 2017-11-08 publication geonetwork.thesaurus.local.theme.atlantos_element temperature and salinity of the water column wave height and period sea surface currents horizontal velocity of the water column sea level biogeochemecal parameters Chlrophill-a fluorescence oxygen bbp irradiance nitrate pH Air temperature Air humidity Atmospheric pressure Chlorophyll-a and fluorescence Currents Dissolved organic matter Nitrous oxide Nutrients Oxygen Salinity Suspended particulates Sea Level Transient tracers Temperature Waves Wind direction Wind speed AtlantOS Essential Variables 2017-02-16 publication geonetwork.thesaurus.external.parameter.NVS.A05 See Copernicus Marine Environment Monitoring Service Data commitments and licence at: http://marine.copernicus.eu/web/27-service-commitments-and-licence.php No limitations on public access vector utf8 oceans -180 180 -90 90 1950-01-01T00:00:00 http://marine.copernicus.eu WWW:LINK CMEMS web site http://www.marineinsitu.eu/dashboard/ WWW:LINK CMEMS INS TAC Dashboard CMEMS INS TAC Dashboard http://nrt.cmems-du.eu/oceanotron/ WWW:LINK Access to observation collections : INS-CORIOLIS-GLO-NRT-OBS_* Oceanotron Server - in-situ observation data http://my.cmems-du.eu/thredds/CORIOLIS-GLOBAL-CORA-OBS/CORIOLIS-GLOBAL-CORA-OBS.html WWW:LINK THREDDS Server - CORA products THREDDS Server - CORA products http://nrt.cmems-du.eu/thredds/catalog.html WWW:LINK THREDDS server - gridded analysis THREDDS server - gridded analysis For the Near Real Time products generated by the CMEMS INSTAC the data are transmitted within 24hours to a week from acquisition depending of the plaftforms and networks .

For the products elaborated for re-analysis activities ( Mainly Temperature and Salinity parameters ) they are assessed using both statistical methods that allow to check their consistency with the neighbour measurements and the outliers are checked by scientists that are able to determine if it’s a real oceanographic feature or a sensor anomaly( drift or offset) Suspicious measurements are fllgged as bad . .
