| Temperature (T), dew-point and the derived critical temperature (Tcrit, red line). Contrails are likely to be formed at levels, where Tcrit > T. The critical temperatures are calculated using a standard contrail factor CF=0.037 g/kgK. The sounding altitude is shown in the ordinate as meters above sea level. | |||||||||
