These data originate from the stations of the DWD as well as legally and qualitatively equivalent partner networks. Up to and including the complete previous year of the edition date, the data have finally passed through quality control and have been versioned. For more recent data, quality control has not yet been completed. All times are in UTC. According to the SYNOP convention, the hour hh denotes the measurement of hh-10min (so UTC11 denotes the time UTC10:50).

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.
