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 31°N at a depth of around 600 m and at around 35°N at a depth of around 200 m.
