To ensure consistent time series of climate observations, the German Meteorological Service (DWD) operates out parallel measurements (e.g. wind and precipitation measurements) at reference stations. Parallel subsequent generations operational measurement systems are carried over several years selected ten locations with different environmental conditions in order to evaluate quality data obtained, analyse systematic differences between instrument types homogeneity series.A key feature observations is that they monitored consistently long periods a high degree comparability observations. Inconsistent limited use research. In assess consistency these must be described detail using metadata and, particular, by reliably specifying uncertainties. The overall objective measurements, especially before after sensor changes, develop necessary automated procedures detect breaks caused changes homogenise series.
