| Zusammenfassung |
| Air traffic is a source of trace gases in the
upper troposphere and lower stratosphere. Contrails readily form from water
vapor exhausts under favorable meteorological conditions. Since contrails are
ice crystal clouds like natural cirrus clouds, they bear a greenhouse potential
which has to be investigated. The IFU has built a scanning lidar system
employing a pulsed Nd:YAG laser as the emitter and a 52-cm diameter telescope as
the receiver. Signals are processed in several channels to investigate
depolarization and wavelength dependencies of the light backscattered from ice
crystals. These investigations are aimed at the formation and life cycles of
contrails, their optical properties, and their climatological consequences in
areas of dense air traffic. The experimental lidar setup is described and a
sample measurement is shown. |
