Results of QC

A total of 13 profiles (292 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 292

Position on land test

On land: 0 of 13

Invalid position: 0 of 13

Regional range test

Error data (low): 0 of 292

Error data (high): 0 of 292

Gradient test

Error data: 0 of 292

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

Summary of QC

No errors were detected with JMA's quality control procedures.
There were differences above 2°C between observation data and the results of assimilation around 34°N at a depth of around 300 m.
There was no significant bias in comparison with the results of assimilation by JMA.
