NWS, FAA Picks DUALDoppler Provider to Upgrade Radars

Unlike conventional radar systems, which transmit solely a horizontal scan, dual-polarimetric radars send out both vertical and horizontal polarized beams, and enable meteorologists to see twice as much data than they can with systems not employing this technique. They also provide more accurate information about the size, shape, orientation and state of precipitation.

Broadcast television stations that implement dual-polarimetric technology receive improved weather detail, achieve higher resolution imaging and increase the accuracy and precision in their forecasting
