Number of hail days

The data contain the monthly and yearly number of hail days and the long-term average number of hail days per year or per month of the summer half-year (April to September), per km2. Hail cannot be measured on the ground over a wide area. The size is derived from radar measurements. A hail day is defined as a day on which a high probability of hail on the ground was concluded from the radar measurements (based on radar parameter POH). The 24 hours between 06 UTC and 06 UTC of the following day are considered. DOI:
