Results of QC

A total of 26 profiles (875 data, reported by BATHY or TESAC) were received from the PACIFIC TRIANGLE.
The results of JMA quality control are as follows.

Grounded test

Error data: 0 of 875

Position on land test

On land: 0 of 26

Invalid position: 0 of 26

Regional range test

Error data (low): 0 of 875

Error data (high): 0 of 875

Gradient test

Error data: 0 of 875

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 was no significant bias in comparison with the results of assimilation by JMA.
There were differences above 2°C between observation data and the results of assimilation at a depth of around 150 m in the seas around Indonesian Maritime Continent.
