Several organizations teamed to conduct the first multiple, unmanned aircraft interception of a telltale rush of cold air preceding a thunderstorm at the Pawnee National Grassland in northeast Colorado on Aug. 14, 2014.
The international research effort, organized by the University of Colorado Boulder’s Research and Engineering Center for Unmanned Vehicles (RECUV), also involved the University of Nebraska-Lincoln, Texas Tech University, Colorado State University, the University of Tübingen in Germany and the Center for Severe Weather Research based in Boulder. A gust front is a boundary that separates a cold thunderstorm downdraft from warm, humid surface air, which is of interest to scientists because it can generate damaging wind speeds up to 100 miles per hour.
“We believe this was the first time multiple unmanned aircraft systems were flown simultaneously to make coordinated measurements of the outflow from an evolving thunderstorm,” said CU-Boulder postdoctoral fellow Jack Elston.
Elston is the principal investigator and organizer of the National Science Foundation-sponsored Multi-sUAS Evaluation of Techniques for Measurement of Atmospheric Properties field experiment, or MET-MAP. RECUV is a university, government and industry partnership headquartered in CU’s aerospace engineering sciences department.
