Short summary
In order to analyze the impact on long time series by the transition from manual to automatic sunshine duration devices, parallel measurements of German climate reference stations are used. The different measurement principles (glass sphere and photodiode) cause systematic differences between the observations. With a linear regression model (used to adjust the automatic measurements) we want to prevent breaks in long time series of daily sunshine duration.
