| Abstract: | This review describes the new results of analysis of both the physicochemical properties of soot particles emitted by commercial aircraft and subsequent variations in these properties under aircraft-contrail conditions. The results of the study of model laboratory soot samples are given for comparison. The state-of-the-art level of experimental studies of hygroscopicity of soot particles and their efficiency as crystallization centers are presented. The ability of soot aerosols to form condensation nuclei in aircraft contrails and ice nuclei in the upper troposphere is estimated. The estimates of the effects of aircraft soot emissions into the atmosphere are given. |
