  1. Quality control and dissemination of real time data - methodology andadvanced available technological tools the Coriolis data centreexperience Gilbert Maudire, Loïc Petit de la Villéon, Catherine MaillardSEAMER 2000

  2. Pre-operational and Operational Oceanographic Programmes • Pre-operational data management TOGA-WOCE-CLIVAR Global Subsurface Data Centre • CORIOLIS-ARGO real-time data processing • Pommier, Pomme • GYROSCOPE (Atlantic) • MFSPP (Mediterranean)

  3. New Questions Asked • Access to observational data of temperature within 12 hours after their production • Access to other types of data within 48 hours within their production • Access to statistics, gridded data, combinations with delayed mode data, graphs, maps and products • Assess a standardised level of quality to the data

  4. Sensors currently producing time data • Lagrangian profilers : PROVOR, APEX.. • XBt, Xctd • Thermosalinographs

  5. CORIOLIS Data Centre • to process European floats • provor • other floats • to combine various in-situ measurements • to insure interoperability with argo data centres • data formats • common quality procedures • real time data exchanges • to gather global data sets for European users Partners : IFREMER, SHOM, IRD (ORSTOM), METEO-FRANCE, CLS-ARGOS

  9. quality control • complies with international recommendations • IOC, ICES, MAST • two levels • automatic control • visual control for dubious profiles • gtspp quality flag scale
