Results of QC

A total of 12 profiles (259 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 259

Position on land test

On land: 0 of 12

Invalid position: 0 of 12

Regional range test

Error data (low): 0 of 259

Error data (high): 0 of 259

Gradient test

Error data: 0 of 259

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

Summary of QC

QC detected no unnatural profiles.
There were differences above 2°C at depths of less than 100 m. The observation data showed sharper thermocline better than the assimilation data.
