A proposal to use drones to study study severe storms has received a boost from a $1.9 million federal grant to refine the aircraft and some of the instruments they carry.
University of Colorado researcher Eric Frew said Wednesday the National Science Foundation grant will allow CU and four other schools to develop guidance systems that maximize the drones' flight time.
The grant will also help develop some of the instruments the drones would carry.
The latest news from around North Texas.
Test flights would be done over tornado-prone states in the West and Midwest.
The other schools involved are Texas Tech, Texas A&M, the University of Nebraska Lincoln and the University of Minnesota.
Researchers say drones can penetrate parts of storms that other instruments can't reach, at less cost and with less danger than piloted planes.
