DOW
Doppler on Wheels

The Doppler on Wheels (DOW) is a network of mobile Doppler radars operated by the Center for Severe Weather Research (CSWR). DOW includes three dual-frequency, dual-polarization radars that operate in the X-band frequency range (9.35-9.55 GHz). They feature a narrow beam (0.8-0.9 degrees), rapid-scan capabilities, and a gate spacing of 15 to 600 meters. DOW radars are mounted on 7500 series International Workstar Trucks and can be easily deployed to various locations to gather radar measurements of meteorological phenomena such as tornadoes, hurricanes, and microbursts. Since its inception in the 1990s, the DOW has participated in numerous research and educational programs. It has been part of the National Science Foundation (NSF) Lower Atmospheric Observing Facilities (LAOF) program since 2008.
