The National Weather Service is currently upgrading their pulsed radar network to dualpolarization radars. WSR-88D radars emit and receive pulses that have horizontal orientations. Dual-polarization radars also transmit and receive data in the vertical direction, providing a more complete picture of atmospheric targets.This technology allows forecasters to:Identify non-weather targets more easily Differentiate rain, snow, and melting snow Detect when hail is present in a thunderstorm
