Results of QC

A total of 46 profiles (1018 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 1018

Position on land test

On land: 0 of 46

Invalid position: 0 of 46

Regional range test

Error data (low): 0 of 1018

Error data (high): 0 of 1018

Gradient test

Error data: 0 of 1018

Summary of QC

No errors were detected with JMA's quality control procedures.
There was no significant bias in comparison with the results of assimilation by JMA.
There were differences above 3°C between observation data and the results of assimilation in the seas south of 7°N at depth of between 100 and 300 m.
