During a recent snowfall, Richard Born, a retired associate professor from Northern Illinois University, captured a slo-mo video (240 frames/s) of falling snowflakes using his iPhone^® X. The camera was approximately a foot in front of a wooden fence to serve as a background for the falling snow.

With the video analysis features of Logger Pro^™ 3, Richard determined both the wind speed and the terminal velocity of snowflakes. His video captured the (x,y) position over time for a dozen snowflakes, and each snowflake was captured in its own series.
