The paper presents the principles of measuring the precipitation characteristics imaging and analyzing precipitation particle shadows. The method of precipitation type determination is described. It is based on microstructure characteristics measurements using the optical precipitation gauge. The measurements of the size and velocity ratios for rain and snow precipitation particles are presented.
