Data processing |
: |
Raw data from monitoring device (6 s) are processed to half-hour-mean values and transmitted hourly to the central air quality data base.
Corrections of zero and span deviations after calibration each year |
Processing for averaging |
: |
Processing for Daily Data: Daily data check for function control and plausibility Processing for Monthly Data: Monthly data check for function control and plausibility |
Data flag |
: |
"Valid" (>50% raw data), "no valid" (<50% raw data, or device out of operation). |
