C5 - Radar-based spatial climate data
The following grid data products are derived from radar data, which were further processed for statistical statements with the use of the HailStoRe resampling approach, among other things (see links for detailed product documentations). The hail climatology was developed in a user-oriented manner in a public-private partnership and represents a nationally uniform basis for the risk assessment of hail events.
The following data are planned to be made available in May 2025:
