Dual-Pol is Coming to the ArkLaMiss!
The National Weather Service is currently in the process of upgrading its nationwide Doppler radar network to include Dual Polarization (commonly referred to as Dual-Pol) technology. This is the most significant upgrade to the National Weather Service radar network since the late 1980s and early 1990s, when the WSR-88D deployment took place. Several radar sites around the country have already been upgraded, including the Columbus AFB radar in Monroe County and the Mobile radar in Mobile, AL. The Jackson area radar in Brandon is in the upgrade process now. During the upgrade process, radar data from each site will be unavailable. However, you will still be able to view radar data from surrounding sites.
Prior to the dual-pol upgrade, NWS radar transmits horizontal pulses, which give a measure of the horizontal dimension of clouds and precipitation. Dual pol radar transmits radio wave pulses that have both horizontal and vertical orientations, providing additional information on the size and shape of particles being detected by the radar. This additional information can be used in turn to improve rainfall estimates, help determine precipitation type, and better detect certain types of hazardous weather. The upgrade will add several new products to the existing suite of data provided by the WSR-88D.
