The Snowflake Video Imager (SVI) is a ground-based imaging system developed at Wallops Flight Facility (WFF). It records greyscale imagery of snowflakes to determine snowflake size and orientation distribution. It can operate autonomously in harsh winter conditions with winds up to 50 knots and temperatures as low as -40 degrees Celsius. SVI has a high frame rate of 60 Hz and a nominal pixel size of 0.05 mm by 0.1 mm.
