NEXRAD is a system of 159 high-resolution weather radars operated by the U.S. government agencies for detecting precipitation and atmospheric movement. It was developed and deployed from 1988 to 1997, replacing the previous WSR-57 and WSR-74 radars.
Known as "Early Warning Pinpoint Doppler", this is based on top of a terminal building at Bradley International Airport in Windsor Locks, Connecticut. Eventually, live NOAA National Weather Service radar data from several regional sites began to be used interchangeably with WFSB's radar and was branded on WSHM as "Pinpoint Doppler".
Doppler radar uses the Doppler effect to produce velocity data about objects at a distance by bouncing a microwave signal off them and analyzing how the frequency of the returned signal changes. Learn about the concept, technology, history and applications of Doppler radar in various domains like aviation, police radar detectors, navigation, meteorology, etc.
Weather radar, also called Doppler weather radar, is a type of radar used to locate and estimate the type of precipitation, such as rain, snow, or hail. Learn about the history, types, and applications of weather radar, and how it can detect severe weather and storms.
WSR-74 was a series of weather radars designed in 1974 for the National Weather Service. They operated in C or S band and were used for local or national warnings until the 1990s.
dBZ is a logarithmic dimensionless unit used in radar to compare the equivalent reflectivity factor (Z) of a remote object to a raindrop. It is proportional to the number and size of reflectors and helps to estimate the rain or snow intensity and type.
Doppler on Wheels (DOW) is a fleet of truck-borne radars affiliated with the University of Illinois and led by Joshua Wurman. DOWs have been used to collect data in tornadoes, hurricanes, and other phenomena since 1995, and have contributed to many scientific discoveries and field projects.
6.59 acres (2.67 ha) [2] [3] The Louis Blotner Radar Site was a tracking site (Not an RBS site) in Connor, Maine at the former NIKE missile launch site. Activated in June 1963 and operational until after 1979, The Ashland site was an AUTOTRACK radar site operated by Detachment 7 of the 1st Combat Evaluation Group . [ 4 ]
