Results of QC

A total of 20 profiles (669 data, reported by BATHY or TESAC) were received from the NORTHEWEST SANDERLING.
The results of JMA quality control are as follows.
  • Grounded test
  • Error data: 0 of 669

  • Position on land test
  • On land: 0 of 20

    Invalid position: 0 of 20

  • Regional range test
  • Error data (low): 0 of 669

    Error data (high): 0 of 669

  • Gradient test
  • Error data: 0 of 669

For details of JMA's quality control procedures, please refer to this page.


Summary of QC

  • QC detected no unnatural profiles.
  • At depths of between 50 and 200 m in areas around 7°N, there were differences above 3°C between observation data and the results of assimilation. The observation data showed sharper thermocline than the assimilation data.
