Kvalobs range control (QC1-1) on relative humidity (UU)

The distribution of all UU measurements follows a Poisson distribution with deviations in the upper and lower end. From the assumption that the deviations consist of error values mostly, the range control values is chosen.

• UU less than 5% is rejected
• UU between 5% and 10% is flagged as very suspicious (probably wrong)
• UU between 10% and 15% is flagged as somewhat suspicious (probably correct)
