| Data processing |
: |
Only technically false data are rejected. |
| Processing for averaging |
: |
Processing for Hourly Data:
Arithmetic hourly means of half an hour avarage values calculated by means of the 5-second values.
Processing for Daily Data:
Arithmetic daily means are calculated from valid hourly data if 16 hourly data of 24 hours during the month are valid.
Processing for Monthly Data:
Arithmetic monthly means are calculated from valid daily data if 20 daily data of 30 days during the month are valid. |
