Results of QC

A total of 325 profiles (168387 data, reported by BATHY or TESAC) were received from the CAP PASADO.
The results of JMA quality control are as follows.
  • Grounded test
  • Error data: 1141 of 168387

  • Position on land test
  • On land: 0 of 325

    Invalid position: 0 of 325

  • Regional range test
  • Error data (low): 0 of 168387

    Error data (high): 0 of 168387

  • Gradient test
  • Error data: 6 of 168387

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 are found in the seas near the west coast of the United States (Refer to concerned figures). The topography used our grounded test is too rough to catch the error.
  • There are large differences at depths of between 100 and 200m in the seas south from 10°N. The observation data shows sharper thermocline better than the assimilation data.
  • With the exception of the above errors and differences, there were no significant biases in comparison with the results of assimilation by JMA.
