Results of QC

A total of 80 profiles (67028 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 67028

Position on land test

On land: 0 of 80

Invalid position: 0 of 80

Regional range test

Error data (low): 0 of 67028

Error data (high): 0 of 67028

Gradient test

Error data: 20 of 67028

For details 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 were differences above 2°C between the results of assimilation and a profile data observed at depths of between 100 and 300m in the seas west from 147°W.
With the exception of the above errors and differences, there were no significant biases in comparison with the results of assimilation by JMA.
