What is dual pol radar?
What is dual pol radar?
Dual-polarimetric radar transmits and receives pulses in both a horizontal and vertical orientation. As a result, the returning frequencies provide measurements of the horizontal and vertical dimensions of targets, supplying forecasters with better estimates of the size, shape, and variety of targets.
What makes the new dual pol radar more effective in differentiating between rain and snow?
Dual-pol radar sends and receives both horizontal and vertical pulses, providing a much more informative two-dimensional picture of whatever is out there. This information helps forecasters clearly identify rain, hail, snow or ice pellets, and other flying objects, improving forecasts for all types of weather.
How many Doppler radars are in the US?
There are 155 WSR-88D Doppler radars in the United States, including the U.S. Territory of Guam and the Commonwealth of Puerto Rico. Most radars are operated by the NWS or the Department of Defense. Click here to view a map of the WSR-88D Doppler Radar network.
What is differential reflectivity?
Definition: Differential Reflectivity is the logarithm ratio of the horizontally polarized reflectivity to the vertically polarized reflectivity. Positive values of ZDR indicate that dominant hydrometeors are larger in the horizontal than in the vertical.
What is the most accurate radar app?

What are the benefits of dual-pol radar?
Dual-pol radar provides measurable benefits to: Polarimetric radar… can significantly improve the accuracy of the estimates of amounts of precipitation. can tell the difference between very heavy rain and hail, which will improve flash flood watches and warnings.
What does dual polarization mean for radar?
Dual Polarization Radar. Dual-polarization, or dual-pol, is part of the NWS vision to build a weather-ready nation to better protect lives and livelihoods. This new technology provides 14 new radar products that will support our mission to serve our partners and customers in Central Alabama.
How does Dual-Pol technology work?
With dual-pol technology, the picture becomes two-dimensional because the radar sends both horizontally and vertically polarized electromagnetic waves.
What does the WSR-88D dual-pol upgrade include?
LOADING… The dual-pol upgrade brings several new radar products to the existing suite of products provided by our WSR-88Ds. In addition to three new base products, there are also several new products which are derived from the new dual-pol products and existing radar products.
