Results of QC

A total of 30 profiles (636 data, reported by BATHY or TESAC) were received from the RYOFU MARU III.
The results of JMA quality control are as follows.
  • Grounded test

    • Error data: 0 of 636

  • Position on land test

    • On land: 0 of 30

    Invalid position: 0 of 30

  • Regional range test

    • Error data (low): 0 of 636

    Error data (high): 0 of 636

  • Gradient test

    • Error data: 0 of 636

Summary of QC

  • QC detected no unnatural profiles.
  • There were differences above 2°C at depths of between 50 and 250 m. The observation data showed sharper thermocline better than the assimilation data.
