I may have missed it, but how do you deal with temporary steps in the time series? For example from aging of the screens, replacement of the screens, and then returning aging of the screens.

If temporary steps in the data series from aging effects are treated the same as permanent changes, such as changes in location or instrumentation, then you will add the aging effects at each breaking point. This leads to a large error over many homogenization corrections.
