Alberta Hail Project
The main instrument in this research was an S-band circularly polarized weather radar located at the Red Deer Industrial Airport in central Alberta, Canada.Numerous researchers have used the dataset and during the period 1990 to 1994, 23 publications appeared in journals and conferences, as well as 4 scientific reports were prepared.The project area covered 33,700 km2 and was centred on the Penhold radar site located near the Red Deer Airport (52°12′N 113°54′W / 52.2°N 113.9°W / 52.2; -113.9).Each spring, approximately 20,000 farmers in the project area would receive cards to record any event of hail, including its size.In addition to upper-air sounding data, the surface temperature and dewpoint (representative of the storm's inflow) were obtained from a mesonetwork.
