Results of QC

A total of 15 profiles (505 data, reported by BATHY or TESAC) were received from the NORTHEWEST SANDERLING.
The results of JMA quality control are as follows.

Grounded test

Error data: 0 of 505

Position on land test

On land: 0 of 15

Invalid position: 0 of 15

Regional range test

Error data (low): 0 of 505

Error data (high): 0 of 505

Gradient test

Error data: 0 of 505

Summary of QC

QC detected no unnatural profiles.
There was no significant bias in comparison with the results of assimilation by JMA.
