The cloud microphysical characteristics with aircraft icing during 7 flights are analyzed. The cloud phase, liquid water content, median volume diameter and the concentration of supercooled large droplets are described in detail. The aircraft icing potential monitoring technology which combines satellite, numerical model outputs and surface observations are introduced. In comparison with 20 icing reports during 2000-2010, it is found that it can detect 90% of icing correctly. The aircraft icing on 26 October 2010 is analyzed. Finally, the aircraft icing monitoring system based on aircraft icing potential detection technology is showed. The system determines the products of aircraft icing potential with horizontal resolution of 20 km, vertical resolution of 25 hPa, and temporal of 1 h. So, this system can be used in actual operations.
