Measurements of Drifting Snow Particles

Abstract

The use of wide trenches, box-type drift gauge, Chest-of-drawer-type drift collecttor, saltation gauge, cyclone-type drift collector, net-type drift collector and photoglaphic observation, are some of the methods used to attempt blowing snow particles measurements. This report explains aforementioned methods, and shows the limits and problems of these methods.
On the other hand, the author outlines a recently developed Snow Particle Counter (SPC) which is useful automatic meter for blowing snow particles measurements, and intends to summarize his recent works on the improvement of SPC.
