The results of JMA quality control are as follows.

Grounded test

Error data: 0 of 208

Position on land test

On land: 0 of 7

Invalid position: 0 of 7

Regional range test

Error data (low): 0 of 208

Error data (high): 0 of 208

Gradient test

Error data: 0 of 208

Summary of QC

QC detected no unnatural profiles.
One of the observations at around 6°N, 129°E was considered to be erroneous data.
