Data Processing

1. All data with obvious sampling or instrument operation problems are rejected.
2. The hourly data divide into two groups, background and pollution, by a statistical method.
3. To eliminate local effect, the hourly data in the following wind sectors are rejected.
WD=67.5° with wind speed < 22 m/s
WD=22.5, 45, 90, 112.5° with wind speed < 11 m/s
wind speed < 3 m/s
4. The daily data with the number of hourly data less than 7 are rejected.
5. Daily data are calculated from selected hourly data.
6. Monthly data are calculated using the daily data.

Processing for averaging

[Hourly] 1. All data with obvious sampling or instrument operation problems are rejected.
2. The hourly data divide into two groups, background and pollution, by a statistical method.
3. To eliminate local effect at a pollution group, the hourly data in the following wind sectors are rejected.
WD=67.5° with wind speed < 22 m/s
WD=22.5, 45, 90, 112.5° with wind speed < 11 m/s
wind speed < 3 m/s
4. The daily data with the number of hourly data less than 7 are rejected.
[Daily] Daily data are calculated from selected hourly data.
[Monthly] Monthly data are calculated using the daily data.
