These data are generated by combining satellite-based and surface-measured data of the surface irradiance (global radiation) and the sunshine duration. The associated algorithms have been developed within the DUETT-project and are continuously adjusted and improved. Gridded data (EPSG-3035 projection, Germany) of the surface irradiance and the sunshine duration are generated with a spatial resolution of 1 km and a temporal resolution of 1 hour (average / sum for synoptic hours, ending at minute 50). 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.

The associated algorithms have been developed within the DUETT-project and are continuously adjusted and improved. Gridded data (EPSG-3034 projection, Germany) of the surface irradiance and the sunshine duration are generated with a spatial resolution of 2 km and a temporal resolution of 1 hour (average / sum for synoptic hours, ending at minute 50). 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 network stations. Extensive station metadata, such as station relocations, instrument changes, reference time changes, algorithm changes or operator information are included. The quality check for these data has been completed.

HYRAS-DE-RSDS is a global radiation product for Germany in a 5 km x 5 km grid for the period 1951-2020 and is based on daily measured values of sunshine duration and global radiation. 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 solar incoming radiation includes the direct and the diffuse part of the solar radiation with respect to the horizontal plane. It is sometimes also referred to as "shortwave", including the solar spectrum up to 2.8 micron, as opposed to "longwave", which refers to the thermal radiation of the atmosphere.

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 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. It should be noted that the data was interpolated bilinearly from ETRS:3034 to ETRS:3035, as the other products are available in ETRS:3035.
