The data are quality checked by a standardised method.
Climate Parameter Quality Check for site Pasto Abraham
Checking modules:
1. Does a value exist?
Quality flag is set to
"d = missing"
2. Checking of site specific threshold value.
If the value is not inbetween the thresholds the quality flag is set to "c = out of range":
Air temperature in 2m max = 30
Air temperature in 2m min = 10
Air humidity max = 100
Air humidity min = 10
3. Checking the plausibility of air temperature and air humidity within the measurement intervals by comparing the previous and current values.
If the temperature amplitude is higher then 10°C and humidity amplitude is higher than 30% the plausibility of this variation is checked by comparing to the variation of the other parameter.
The quality flag is set to "e = variation implausible".
4. Precipitation check
If precipitation is more than 25 mm then quality flag is set to "c = out of range"
If precipitation is more than 15 mm and air temperature increases more than 0.2 °C inbetween a temporal interval then quality flag is set to "e = variation impossible".
5. Relative air humidity values are corrected by a standarized method and quality flag is set to "m = manually corrected".
All other values are set to "a = valid".
