Aviation induced diurnal North Atlantic cirrus cover cycle

Aviation induced cirrus (AIC) cover is identified from mean diurnal cycles of cirrus cover and air traffic density in the North Atlantic flight corridor. Traffic data for this region show an aviation �fingerprint� with two maxima during morning eastbound and afternoon westbound traffic. Th...
