Results of QC

A total of 19 profiles (395 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 395

  • Position on land test
  • On land: 0 of 19

    Invalid position: 0 of 19

  • Regional range test
  • Error data (low): 0 of 395

    Error data (high): 0 of 395

  • Gradient test
  • Error data: 0 of 395

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


Summary of QC

  • QC detected no unnatural profiles.
  • The observation data has deeper mixed layer and sharper thermocline than the assimilation data in the seas south from 10°N.
