Results of QC

A total of 254 profiles (110306 data, reported by BATHY or TESAC) were received from the CPO NEW YORK.
The results of JMA quality control are as follows.
  • Grounded test
  • Error data: 0 of 110306

  • Position on land test
  • On land: 0 of 254

    Invalid position: 0 of 254

  • Regional range test
  • Error data (low): 0 of 110306

    Error data (high): 20 of 110306

  • Gradient test
  • Error data: 25 of 110306

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


Summary of QC

  • QC detected some unnatural profiles shown in 'Results of QC'.
  • Among the data that passed QC, some "hitting bottom" data were found in the seas near the west coast of the United States (Refer to concerned figures). The topography used for our grounded test is too rough to catch the error.
  • There were large differences at depths of between 30 and 200 m. The observation data shows sharper thermocline than the assimilation data.
