Results of QC

A total of 16 profiles (363 data, reported by BATHY or TESAC) were received from the KEIFU-MARU.
The results of JMA quality control are as follows.
  • Grounded test

    • Error data: 0 of 363

  • Position on land test

    • On land: 0 of 16

    Invalid position: 0 of 16

  • Regional range test

    • Error data (low): 0 of 363

    Error data (high): 0 of 363

  • Gradient test

    • Error data: 0 of 363

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.
