Abstract:

Laser transmission through a snowfield has been measured in a laboratory experiment. Simultaneous measurements of the attenuation of a 0.6328- and a 10.6-micrometer wavelength laser beam by a common snowfield are reported. The results are favorably compared with a prediction of an analytic model which treats the snowflakes as spheres. The analytic model is then restructured and applied to predict the attenuation which would be obtained in a natural snowfield.
