For analyzing trends in extreme events, homogenized sub-daily temperature series are re-quired. However, homogenization methods for sub-daily data are only now being devel-oped. Most current approaches rely on statistical methods to correct inhomogeneities, but extreme events may be affected differently by errors than the bulk of the data and hence other approaches may be more suitable. Here we propose to further develop a new correc-tion method for sub-daily temperature time series that relies, at least partly, on a very simple physical model of the underlying error. The method has been developed for the case of the change of the shelter from a Wild screen to a Stevenson screen, which is a frequent reason for inhomogeneities in Central and Eastern European series. As the method was developed for one specific case (Basel, Switzerland), it first needs to be demonstrated that the approach is applicable to other stations. Here we propose to apply the method to other Swiss series, to adapt and to simplify it, and to compare it with other, statistics-based ap-proaches in order to prepare for a future, more widespread application of the approach. Finally, the change from conventional observations in a Stevenson screen to automated stations, a network-wide change that took place in the late 1970s, will be analysed based on a 30-yr series of parallel measurements from Basel using the same basic approach.
