Safer winter driving with snowflake imaging
Camera system captures critical data about falling snowflakes which can help improve weather radars and snowfall prediction accuracy
October 4, 2017
Falling snow makes winter driving a challenge. Transportation planners, road crews and emergency managers can now estimate real-time accumulations with active imaging from multi-angle snowflake cameras (MASC). NSF-funded research led to development of MASC, which images snowflakes down to the diameter of a human hair and simultaneously measures how fast they fall. These data have been critical for verifying snowfall predictions and winter precipitation algorithms for weather radars.
