Dual pol radar sends both horizontal and vertical pulses, providing a twoâ dimensional view. The last row contains various dual pol images. Conventional Doppler radar sends out a horizontal energy pulse providing a oneâ dimensional view of precipitation. The images below show various products and data from the NWS Louisville Doppler radar. Farther south, freezing rain accumulated, while little or no precipitation was falling at this time over parts of south-central Kentucky (area of black).
