Part-time operations at the new office began in September 1994, and a WSR-88D radar was installed on November 2 of that year. Full-time operations at the forecast office began on February 20, 1995. [2] Shortly thereafter, on March 1, 1995, the Quad Cities office's county warning area expanded from 12 to 34 counties – 21 in Iowa and 13 in ...
Coastal ocean dynamics applications radar (CODAR) is a type of portable, land-based, high frequency (HF) radar developed between 1973 and 1983 at NOAA's Wave Propagation Laboratory in Boulder, Colorado. CODAR is a noninvasive system that can measure and map near-surface ocean currents in coastal waters. It is transportable and can produce ocean ...
NEXRAD or Nexrad (Next-Generation Radar) is a network of 159 high-resolution S-band Doppler weather radars operated by the National Weather Service (NWS), an agency of the National Oceanic and Atmospheric Administration (NOAA) within the United States Department of Commerce, the Federal Aviation Administration (FAA) within the Department of Transportation, and the U.S. Air Force within the ...
A SuperDARN radar site located in Saskatoon, Canada. The Super Dual Auroral Radar Network (SuperDARN) is an international scientific radar network [1] [2] consisting of 35 [3] high frequency (HF) radars located in both the Northern and Southern Hemispheres.

Since its initial usage in May 1999, the National Weather Service (NWS) in the United States has used the tornado emergency bulletin — a high-end classification of tornado warning — sent through either the issuance of a warning or via a "severe weather statement" that provides updated information on an ongoing warning—that is issued when a violent tornado (confirmed by radar or ground ...
The frequency separation is chosen to give a “spatial beat” length which is in the range of the water waves of interest. The dual frequency radar may be considered a microwave equivalent of the high frequency (HF) radar (see below). The dual frequency radar is suitable for the measurement of surface current.
The frequency of radio waves used by most radars, in the form of microwaves, travel in straight lines.This generally limits the detection range of radar systems to objects on their horizon (generally referred to as "line of sight" since the aircraft must be at least theoretically visible to a person at the location and elevation of the radar transmitter) due to the curvature of the Earth.
