Results of QC

A total of 26 profiles (10786 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 10786

Position on land test

On land: 0 of 26

Invalid position: 0 of 26

Regional range test

Error data (low): 0 of 10786

Error data (high): 0 of 10786

Gradient test

Error data: 0 of 10786

Summary of QC

QC detected no unnatural profiles.
There were differences above 2°C at a depth of about 200 m in the seas around 146°W. The observation data showed sharper thermocline than the assimilation data.
