Results of QC
A total of 44 profiles (1409 data, reported by BATHY or TESAC) were received from the PACIFIC TRIANGLE.
The results of JMA quality control are as follows.
The results of JMA quality control are as follows.
- Grounded test
- Position on land test
- Regional range test
- Gradient test
Error data: 0 of 1409
On land: 0 of 44
Invalid position: 0 of 44
Error data (low): 0 of 1409
Error data (high): 0 of 1409
Error data: 0 of 1409

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 around 2°S at a depth of around 100 m. It's considered to be an erroneous profile.
