Detection of In-flight Icing Conditions by Radar over an Airport

Two sets of approaches to detect the presence of supercooled liquid water (SLW) over an airport area with radars are overviewed. The first set focuses on how scanning radars such as those existing in national networks might provide maps of icing likelihood and perhaps intensity over the approach area. The second set deals with the potential uses of dedicated low-cost vertically pointing radars located at the airport site itself to quantify amounts of supercooled cloud, drizzle, and rain over the airport.
