Identifier urn:xkdc:ds:nl.knmi::radar_hail_warning_5min/1.0/
Lineage statement The probability of hail is determined from the difference between the height of the 45dBZ echo top determined by the radars, and the height of the 0-degree isotherm determined by the Numerical Weather Prediction model HiRLAM.
