Mass flux and visibility observed by snow particle counter

Mass flux of blowing snow was observed with real-time processing using the Snow Particle Counter (SPC) which could measure the number and size of snow particles. Mass flux derived from SPC was in good agreement with the result obtained by a snow trap. The comparison of the real-time mass flux observ...

Description
Summary:Mass flux of blowing snow was observed with real-time processing using the Snow Particle Counter (SPC) which could measure the number and size of snow particles. Mass flux derived from SPC was in good agreement with the result obtained by a snow trap. The comparison of the real-time mass flux observed by SPC and the visual range obtained by transmissometer showed a reasonable correlation. The existence of snow particles whose velocities were faster than the instantaneous maximum wind speed in the field was confirmed.
