NEW DEVICE REVEALS WHAT SNOW LOOKS LIKE IN MIDAIR
University of Utah researchers developed a high-speed camera
system that spent the past two winters photographing snowflakes in 3-D as they
fell – and they don’t look much like those perfect-but-rare snowflakes often
seen in photos.
“Until our device, there was no good instrument for
automatically photographing the shapes and sizes of snowflakes in free-fall,”
says Tim Garrett, an associate professor of atmospheric sciences. “We are
photographing these snowflakes completely untouched by any device, as they
exist naturally in the air.”
