Results of QC

A total of 25 profiles (11000 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 11000

Position on land test

On land: 0 of 25

Invalid position: 0 of 25

Regional range test

Error data (low): 0 of 11000

Error data (high): 0 of 11000

Gradient test

Error data: 0 of 11000

For details of JMA's quality control procedures, please refer to this page.

Summary of QC

QC detected no unnatural profiles.
There were differences above 2°C at a depth of around 50m in the seas around 124°W. The observation data showed shallower mixed layer than the assimilation data.
