This page shows results for the PX46 line based on monitoring by the KEIFU MARU and comparison with the result of assimilation by MOVE-NP.

Overall statistics

Number of profiles	Number of data	AVE	RMSD	MAXD	MIND
8	2808	0.10	0.40	1.56	-1.73

Abbreviations in the table indicate:
AVE: average difference (observation value minus assimilation value)
RMSD: root mean square of difference
MAXD: maximum difference
MIND: minimum difference

Results of QC

A total of 8 profiles (192 data, reported by BATHY or TESAC) were received from the KEIFU MARU.
The results of JMA quality control are as follows.

Grounded test

Error data: 0 of 192

Position on land test

On land: 0 of 8

Invalid position: 0 of 8

Regional range test

Error data (low): 0 of 192

Error data (high): 0 of 192

Gradient test

Error data: 0 of 192

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

Summary of QC

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