Results of QC

A total of 90 profiles (76044 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 76044

Position on land test

On land: 0 of 90

Invalid position: 0 of 90

Regional range test

Error data (low): 0 of 76044

Error data (high): 0 of 76044

Gradient test

Error data: 6 of 76044

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

Summary of QC

Some erroneous profiles are detected by JMA's automated quality control procedures. These are checked by the gradient test.
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 depths of between 100 and 200m.
