Abstract

Measurements were made during December 1981 and January 1982 of backscatter in falling snow at a field location near Burlington, Vermont. These measurements were performed as part of a coordinated measurements program, entitled SNOW ONE-A, which included many other optical and non-optical correlated experiments. The lidar measurements utilized a frequency-doubled Nd:Yag laser yielding 15 mJ pulses at 0.53 μm at a 20 Hz pulse rate. The use of the lidar allowed slant-path (near-horizontal to zenith) measurements of range-resolved backscatter to be made, from which extinction in snow could be deduced.
