Results of QC

A total of 102 profiles (85975 data, reported by BATHY or TESAC) were received from the HORIZON SPIRIT.
The results of JMA quality control are as follows.
  • Grounded test
  • Error data: 0 of 85975

  • Position on land test
  • On land: 0 of 102

    Invalid position: 0 of 102

  • Regional range test
  • Error data (low): 0 of 85975

    Error data (high): 0 of 85975

  • Gradient test
  • Error data: 5 of 85975

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


Summary of QC

  • Some erroneous profiles are detected by JMA's automated quality control procedures. These are checked by the gradient test.
  • 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 depths of between 100 and 200m.
