Weather surveillance radars such as the WSR-88D can detect most precipitation within approximately 80 nautical miles (nm) of the radar, and intense rain or snow within approximately 140 nm. However, light rain, light snow, or drizzle from shallow cloud weather systems are not necessarily detected.
Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.).

Jul 9, 2019 · Doppler radar works a little bit differently from older radars. Instead of merely just measuring the reflectivity of precipitation, it also detects the shape, position, and form as well. By measuring this, a Doppler radar can also measure the velocity of the movement of precipitation toward or away from the radar.
Radar can decipher how far away precipitation is, its speed and how big droplets or snowflakes are. This data can then be used in computer forecasting models to predict future weather trends, while alerting meteorologists to upcoming precipitation, storms or severe weather.
By analyzing the time taken for the pulses to return and their strength upon arrival, the radar system calculates the distance to the precipitation, its type (rain, snow, hail, etc.), and its intensity.
The Weather Surveillance Radar (WSR) - 88D. The most effective tool to detect precipitation is radar. Radar, which stands for RA dio D etection A nd R anging, has been utilized to detect precipitation, and especially thunderstorms, since the 1940's. Radar enhancements have enabled NWS forecasters to examine storms with more precision. The radar ...
