Doppler on Wheels
In the mid-1990s, Doppler weather radar took to the road, thanks to an innovative adaptation that was the brainchild of scientists at the University of Oklahoma and NCAR. Mounted on the back of a flatbed truck and with processing done via laptop, the first Doppler on Wheels (DOW) unit was able to crisscross the country peering into tornadoes, hurricanes, and severe storms. Processing was done on a laptop inside the truck. In the last decade, DOW and its siblings have become a staple of field programs examining tornadoes and other small-scale weather.
