Results of QC

A total of 39(801 levels, reported by BATHY or TESAC) were received from the RYOFU-MARU.
The results of JMA quality control are as follows.
  • Grounded test
  • Error data: 0 of 801

  • Position on land test
  • On land: 0 of 39

    Invalid position: 0 of 39

  • Regional range test
  • Error data (low): 0 of 801

    Error data (high): 0 of 801

  • Gradient test
  • Error data: 0 of 801

Summary of QC

  • No errors were detected with JMA's quality control procedures.
  • There was no significant bias in comparison with the results of assimilation by JMA.
  • There were differences above 2°C between observation data and the results of assimilation at a depth of around 150 m in the seas south of 10°N .
