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.

Based on hourly averages of the wind, multi-year strength wind roses (at least strength wind roses with an annual reference) are created. In order to be able to make representative statements about the wind conditions at a station with the help of a starch wind rose, conditions regarding data availability, continuity of the measuring site, homogeneity of the measuring method and a uniform sensor height per site were taken into account. These data originate from stations of the DWD and legally and qualitatively equivalent partner network stations.

Based on hourly averages of the wind speed and wind direction, multi year strength windroses (at least 5 connected or consecutive years are used) of the relevant stations during the rolling 10 years back are created. In order to be able to make representative statements about the wind conditions at a station with the help of a starch wind rose, conditions regarding data availability, continuity of the measuring site, the homogeneity of the measuring method and uniform sensor height per site were taken into account. Quality conditions are: • at least 85 % of the data are available per month • not any relocation of the measuring site during the evaluation period • not any relocation of the sensor height during the evaluation period • the sensor height is situated within an interval of height from 7 m to 25 m over ground (including outside barriers) These data originate from stations of the DWD and legally and qualitatively equivalent partner network stations.

HYRAS-DE-HURS is a relative humidity product for Germany in a 1 km x 1 km grid for the period 1951 to the previous day and is based on daily measured values of relative humidity. The data set can be used, for example, for the analysis of past climate, for bias adjustment of regionalized climate projection data and as input data for hydrological modeling.

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. The values are average values over the minute, which ends at the time stamp.
