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 arithmetic mean of selected halfhourly data if at least 2/3 of the halfhourly values of one day are available. Processing for Monthly Data: Take the arithmetic mean of selected daily data if at least 2/3 of the daily values of one month are available. |
Data flag |
: |
hourly:
0 = valid value,
3 = invalid data,
6 = calibration |
