Record #96697:

A blowing snow particle detector / T. Brown, J.W. Pomeroy.

Title: A blowing snow particle detector / T. Brown, J.W. Pomeroy.
Author(s): Brown, T.
Pomeroy, J. W.
Date: 1989.
In: Cold Regions Science and Technology. (1989.), Vol. 16(2) (1989)
Abstract: Detector operates at temperatures from above freezing to -40°C and sample range of particle fluxes from within 0.01 m of snow surface to several metres height. Uses 20 mm long, 170 μm radius beam of near-infrared radiation to sense presence of particles, detecting those with radii as small as 22.5 μm and velocities of full range expected for atmospheric flow in Earth's boundary layer. Simple technique for calculating blowing snow flux is developed and tested, using Mie electromagnetic scattering theory, knowledge of inception geometry formed by snow particle and beam, and estimates of snow particle-size frequency distribution.
