Radar-based spatial climate data – Hail
These 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 (for more see the linked 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 2025:
Maximum Hailstone Size
- Monthly and Yearly radar-based Maximum Hailstone Size [Link to a detailed product documentation]
Number of Hail Days
- Monthly and Yearly radar-based Number of Hail Days [Link to a detailed product documentation]
- Monthly and Yearly radar-based Number of Hail Days with Hail >2cm [Link to a detailed product documentation]
- Monthly and Yearly radar-based Number of Hail Days with Hail >4cm [Link to a detailed product documentation]
