NOAA Weather Radio (NWR), also known as NOAA Weather Radio All Hazards, is an automated 24-hour network of VHF FM weather radio stations in the United States which broadcast weather information directly from a nearby National Weather Service office. Its routine programming cycle includes local or regional weather forecasts, synopsis, climate ...
Map of regions covered by the 122 Weather Forecast Offices. The National Weather Service operates 122 weather forecast offices. [1] [2] Each weather forecast office (WFO or NWSFO) has a geographic area of responsibility, also known as a county warning area, for issuing local public, marine, aviation, fire, and hydrology forecasts.
The original "weather" frequency was 162.550 MHz, with 163.275 MHz initially recommended as a backup and later dropped due to interference problems with other federal agencies. NOAA Weather Radio, Weatheradio Canada and SARMEX all refer to the seven stations by their frequencies: 162.400, 162.425, 162.450, 162.475, 162.500, 162.525 and 162.550 MHz.
The Civic Center office closed in 1964, and the main forecast office was relocated at the Wilshire Federal Building where it remained until the current Oxnard location opened in 1993. [ 3 ] An airport station was established at Mines Field (now LAX ) in 1931, with a District Forecast Office established there on April 7, 1947, having relocated ...
The radio frequencies used by Weatheradio Canada are the same as those used by its American counterpart, NOAA Weather Radio (whose parent agency, the U.S. National Weather Service, is also a partner with the Meteorological Service of Canada) and receivers designed for use in one country are compatible for use in the other.
Specific Area Message Encoding (SAME) is a protocol used for framing and classification of broadcasting emergency warning messages. It was developed by the United States National Weather Service for use on its NOAA Weather Radio (NWR) network, and was later adopted by the Federal Communications Commission for the Emergency Alert System, then subsequently by Environment Canada for use on its ...
The working frequency band for HRPT is L Band at 1.670–1.710 GHz and the modulation type isBPSK. [2] On NOAA KLM satellites the transmission power is 6.35 Watts, or 38.03 dBm. [ 3 ] The METOP-A satellite broadcasts with a bandwidth of 4.5 MHz, these use QPSK and AHRPT.
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 ...
