France - Hail Falls Database - Ubyrisk Consultants

Georeferenced Hail fall database> 1 cm in diameter by town in France since 2000.

This database was created from the detections carried out by our Hail Warning France tool. (http://www.catnat.net/services-warning/grele-warning-france), based on the analysis, using a specially developed algorithm internally, of a high resolution radar image crossed with the use of an atmospheric model simulating the conditions of the low layers (temperatures, humidity ... ) in order to characterize the diameter of the hailstones on the ground.

This database, the most exhaustive in the field, references more than 90,000 hail falls > or equal to 1 cm in diameter. The database is updated yearly but it's also possible to get the data of the ongoing year.

The fields appearing in this database are as follows:

• Date

• Town name
• Town code
• Population
• Departemetn number
• Departement name
• Region name
• Longitude
