Results of QC

A total of 76 profiles (45482 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 45482

Position on land test

On land: 0 of 76

Invalid position: 0 of 76

Regional range test

Error data (low): 0 of 45482

Error data (high): 10 of 45482

Gradient test

Error data: 23 of 45482

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 regional range test and the gradient test.
There was no significant bias in comparison with the results of assimilation by JMA.
