Results of QC

A total of 44 profiles (1457 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 1457

Position on land test

On land: 0 of 44

Invalid position: 0 of 44

Regional range test

Error data (low): 0 of 1457

Error data (high): 6 of 1457

Gradient test

Error data: 0 of 1457

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

Summary of QC

QC detected some unnatural profiles shown in 'Results of QC'.
There were differences above 2°C between the results of assimilation and a profile data observed at depths of between 50 and 250m in the seas south from 8°N. It's to be noted that the results of assimilation is considered to be less accurate in the marginal seas.
There was no significant bias in comparison with the results of assimilation by JMA.
