摘要：

By means of a scanning backscatter and depolarization lidar. contrails have been investigated for ages between a few seconds and 60 min. At environmental temperatures less than or equal to -60 degrees C the depolarization measured in the contrails rises from about 0.1 to 0.5 with time, whereas at higher temperatures around -50 degrees C already the youngest contrails exhibit depolarization values of about 0.5. This indicates a strong dependence of the aerosol formation and growth on the environmental temperature which might influence their behavior in the atmosphere.
