This proposed technique is not only useful to observe snowfall quantitatively, but also to measure the kind and quality of solid precipitation. This study focuses on measurement of the diameter and terminal velocity of falling snow particles. The CCD camera has a high shutter speed (1/4000s) so that the shape of each particle can be obtained. Since it is not possible to measure fall velocity using the afterimage of a particle, a new image analysis technique is required. This paper proposes a new image technique to measure fall velocity of snow particles.The results of measurements using these techniques are compared.
