Quality Check Climate Data |
Description
:
|
The data are quality checked (quality flags are set) by a standardised but site specific procedure (developed by R. Rollenbeck):
1. Existence of a value
2. Checking of site specific threshold value for windspeed, global radiation, soil temperature, air temperature and air humidity.
3. Checking the plausibility of air temperature and air humidity changes within the measurement intervals.
4. Precipitation plausibility check.
!!!See the additional information to this dataset for the site specific thresholds and the allocation of the quality flags!!! |
