{"stac_version":"1.0.0","id":"ch.meteoschweiz.ogd-radar-derived-grid","title":"Spatial climate analyses - Hail","description":"Spatial climate analyses describe the spatial distribution and temporal evolution of climate parameters over long periods of time. The hail grid data products are derived from radar data. The hail climatology provides a uniform nationwide basis for the risk assessment of hail events and was compiled using, amongst other things, the statistical resampling method HailStoRe. The following climatologies are available as grid datasets: monthly and annual maximum hailstone sizes; monthly and annual number of hail days for different hailstone sizes; long-term climatologies of hail days with standard deviation; hail risk maps for 2, 5, 10, 20, 30, 50, 70 and 100-year return periods. The hail datasets are calculated exclusively during the hail season (April–September). Further information on the hail climate data can be found in the linked detailed product documentation.
