Table 8: Japanese quality control flags

(Real-time QC flag)*

0- All check passed
1- different from climatology
2- spike, gradient
4- impossible value
8- missing value

*: Add failed test value (eg. value is 3 when "Different from climatology" and "spike")
 

Table 9: Japanese quality control flags

(Delayed-mode QC flag)

0- no QC performed
2- value is good
3- value is questionable
4- value is bad
5- interpolated value
6- corrected by QC
9- missing value
