Three, newly-developed snow characterization instruments are described together with examples of their data products. A snow rate meter was developed that utilizes a sensitive electronic balance to determine snow rate to an accuracy of about ± .05 mm/hr (water equivalent rate) at time resolutions varying from some 15 to 120 s, depending on the wind turbulence situation. A fall velocity indicator was constructed utilizing vidicon TV recording and strobe illumination that permits the fall velocities and fall characteristics of snowflakes to be ascertained. A snow structure recorder was also designed that uses a vidicon camera to look at the detailed crystalline structure of snowflakes (over a 1 cm x 1 cm field of view) that fall on a sampling area which is an intermittently moving belt.
