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 100 m in the seas around Indonesian Maritime Continent.
