PACIFIC TRIANGLE(ELXS8), PX11
Observation period : 2014/7/28 to 2014/8/3

This page shows results for the PX11 line based on monitoring by the PACIFIC TRIANGLE and comparison with the result of assimilation by MOVE-NP.

Overall statistics

Number of profiles	Number of data	AVE	RMSD	MAXD	MIND

Results of QC

A total of 30 profiles (988 data, reported by BATHY or TESAC) were received from the PACIFIC TRIANGLE.
The results of JMA quality control are as follows.

Grounded test

Error data: 0 of 988

Position on land test

On land: 0 of 30

Invalid position: 0 of 30

Regional range test

Error data (low): 0 of 988

Error data (high): 0 of 988

Gradient test

Error data: 0 of 988

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

Summary of QC

No errors were detected with JMA's quality control procedures.
There were differences above 2°C between the results of assimilation and a profile data observed at around 12°N and 2°S. 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.
