Raster data set of global radiation in W/m^2 for Germany - HYRAS-DE-RSDS v4-0

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.

Specific usage

Uncertainties may result from the interpolation method used. Incorrect measurements also result in uncertainties in the grid field. For the interpolation of the grids, a different number of stations were used over time, as the measurement network has changed. This must be considered when comparing different years. 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.

Statement

The raster data set of global radiation (RSDS) is created by a combination of station measurement data (sunshine duration and global radiation), satellite data and ERA5 data. Background fields of global radiation are calculated, using the patterns of the principal component analysis of the CM-SAF dataset, as well as altitude, longitude and latitude in a multiple linear regression. For the station measurement data, sunshine duration measurements are converted to global radiation using an extended Angstrom approach including atmospheric cloud liquid water content from the ERA5 reanalysis data via regression. All results are interpolated by inverse distance weighting.
