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 from 5°N to 10°N.
