  4. Good coverage complementary to other data setsIn 2007 : 465 514 temperature and salinity profiles, 21 million of locations

  5. A new Coriolis Product for re-analysis activities Emilie Brion, Christine Coatanoan 1. Introduction : context and Coriolis 2. A new Coriolis product : reference dataset 3. Conclusion and Overviews 4. Data Access Coriolis Data Center activities • Every 1O days : • more than 3000 floats coming from 10 DACs • 500 to 1500 XBT/CTD/profiles • 10 000 other profiles (eg : TAO/Triton/Pirata) In one year : 63 ships Every week : nearly 800 buoys 5/15

Impossible Speed Test 6. Global Range Test 7. Regional Range Test 8. Pressure Increasing Test 9. Spike Test 11. Gradient Test 12. Digit Rollover Test 13. Stuck Value Test 14. Density Inversion 15. Grey List 16. Gross salinity or temperature sensor drift 17. Frozen profile

  8. Coriolis operations monitored through a dashboard • Since 2007, the dashboard allows a real-time monitoring of operations by a team of operators. (example 1). • The dashboard offers facilities to analyse the yearly/monthly/daily activity of the data centre (example 2). Example 2 : the daily data distribution to Mersea model in April 2008. Nominal behaviour between April 1st and 30th, reasonably stable distribution time duration, with a maximum of 35 minutes on April 16th and minimum time of 16 minutes on April 5th. Example 1 : data distribution activity on May 27th. An operator has to check and diagnose an Argo data distribution anomaly (red smiley).
