What does WSR-88D stand for?
Weather Surveillance Radar-1988 Doppler
Radar stands for Radio, Detection, and Ranging, and has been used to detect precipitation since the 1940’s, with most of the technology coming from the military. The radar used by the NWS is called the WSR-88D, which stands for Weather Surveillance Radar-1988 Doppler (1988 is when the radar was first built).
How many WSR-88D radars are there?
Introduction to the WSR-88D Since first being built and tested in 1988, it has been installed and used operationally at over 160 locations across the United States, including Alaska and Hawaii.

What is the wavelength of the WSR-88D?
approximately 10.7 cm
The WSR-88D’s wavelength is approximately 10.7 cm, so Rayleigh scattering occurs with targets whose diameters are less than or equal to about 7 mm or ~0.4 inch. Raindrops seldom exceed 7 mm so all liquid drops are Rayleigh scatters….
