Results of QC

A total of 34 profiles (1150 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 1150

  • Position on land test
  • On land: 0 of 34

    Invalid position: 0 of 34

  • Regional range test
  • Error data (low): 0 of 1150

    Error data (high): 0 of 1150

  • Gradient test
  • Error data: 0 of 1150

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


Summary of QC

  • No errors were detected with JMA's quality control procedures.
  • There were differences above 2°C between the results of assimilation and a profile data observed at depths of between 50 and 300m in the seas south from 9°N. It's to be noted that the results of assimilation is considered to be less accurate in the marginal seas.
  • There was no significant bias in comparison with the results of assimilation by JMA.
