These data come from DWD stations and legally and qualitatively equivalent partner stations operated for climatological and climate related applications. Extensive station metadata (station relocations, instrument changes, change of reference time, changes in algorithms) are provided with the download via the CDC portal. The measurements are assigned to a timestamp in UTC which marks the end of the 10-minute interval. As of 1.1.2000 the time stamp is given in UTC, for the period before that in CET.

Based on the DUETT gridded data, additional point data is determined at the coordinates of 576 measurement sites of DWD. These pseudo station data are extracted from the gridded data using a simple ‘nearest neighbour’ assignment and are optimized by a subsequent topography correction. This correction is performed using high-resolution topographic data and it primarily captures the possible blocking of direct solar radiation by surrounding mountains. Associated uncertainties are also determined from the gridded data using a ‘nearest neighbour’ assignment and are not subject to any further adjustment in the current program version. The data set is separated into two parts: the directory ./{parameter}/recent/ contains the latest data; in the directory ./{parameter}/historical/ older data are archived.

These data originate from the stations of the DWD and legally as well as qualitatively equal partner networks. Extensive station metadata (station relocations,instrument changes, reference time changes, algorithm changes) are included with the download. The dataset is divided into: - directory ./historical/ , a versioned part with completed quality check - directory ./recent/ , a daily updating part, for which the quality check has not yet been completed - directory ./now/ , an hourly updating part for which the quality check has not yet been completed - directory ./metadata/ , a daily updating part with the metadata about the stations, their instruments and measurement rules.

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.

The quality check for these data has been completed.
