The Shared Mobile Atmospheric Research and Teaching Radars (SMART-R) is a portable doppler radar system that can be mounted to a vehicle. SMART-R consists of two truck-mounted weather radars, allowing researchers to position themselves at short notice close to interesting meteorological phenomena. SMART-R can be used to study precipitation and tropical cyclone (hurricane) development, tracking, intensification, and landfalling impacts. Four weather research institutions collaborate to operate SMART-R: NOAA's National Severe Storms Laboratory, Texas A&M University, Texas Tech University, and the University of Oklahoma.
