The results of JMA quality control are as follows.

Grounded test

Error data: 0 of 263

Position on land test

On land: 0 of 12

Invalid position: 0 of 12

Regional range test

Error data (low): 0 of 263

Error data (high): 0 of 263

Gradient test

Error data: 0 of 263

Summary of QC

QC detected no unnatural profiles.
There were differences above 2°C between observation data and the results of assimilation at a depth of between 80 and 200m in the seas south of 15°N.
