| Zusammenfassung |
Ice crystal clouds have an influence on the
radiative budget of the earth; however, the exact size and nature of this
influence has yet to be determined. A laboratory cloud chamber experiment has
been set up to provide data on the optical scattering behaviour of ice crystals
at a visible wavelength in order to gain information which can be used in
climate models concerning the radiative characteristics of cirrus clouds. A PMS
grey-scale probe is used to monitor simultaneously the cloud microphysical
properties in order to correlate these closely with the observed radiative
properties. Preliminary results show that ice crystals scatter considerably more
at 90° than do water droplets, and that the halo effects are visible in a
laboratory-generated cloud when the ice crystal concentration is sufficiently
small to prevent masking from multiple scattering.
