Results of QC

A total of 64 profiles (28382 data, reported by BATHY or TESAC) were received from the HORIZON ENTERPRISE.
The results of JMA quality control are as follows.

Grounded test

Error data: 0 of 28382

Position on land test

On land: 0 of 64

Invalid position: 0 of 64

Regional range test

Error data (low): 0 of 28382

Error data (high): 0 of 28382

Gradient test

Error data: 0 of 28382

Summary of QC

QC detected no unnatural profiles.
At depths of between 50 and 150 m, there were differences above 2°C between observation data and the results of assimilation. The observation data showed sharper thermocline than the assimilation data.
