These data originate from the stations of the DWD and legally as well as qualitatively equal partner network stations. Extensive station metadata, such as station relocations, instrument changes, reference time changes, algorithm changes or operator information are included. The dataset is divided into a versioned part with completed quality check, in the directory ./historical/. And a part for which the quality check has not yet been completed, in the directory ./recent/. The folder ./timeseries_overview/ contains information about long time series.
