| Data Processing |
| Measurement unit |
: |
ppb |
| Data processing |
: |
All values are quality controlled |
| Processing for averaging |
: |
Processing for Hourly Data:
Only technically biased values are removed (caused by calibration or malfunctioning of equipment).
Processing for Daily Data:
Take the arithmetric mean of selected harfhourly data if at least 2/3 of the halfhourly values of one day are available.
Processing for Monthly Data:
Take the arithmetric mean of selected daily data if at least 2/3 of the daily values of one month are available. |
| Data flag |
: |
Flags put on hourly data are as follows.
1: valid value
6: calibration
9: error code |
