ASR-9 is an airport surveillance radar system admitted into the National Airspace System (NAS), to be utilized by the Federal Aviation Administration to monitor civilian and commercial air traffic within the United States. Developed by Westinghouse, ASR-9 was the first radar system to display air traffic, and weather conditions simultaneously.
In 2002, Bay News 9 was the first TV station in the area to provide a VIPIR Doppler weather radar system. In 2007, Bay News 9 became the first station in Florida, and one of only a handful of stations, to provide a Dual-Pole Doppler Radar system. On Monday, January 5, 2009, Bay News 9 launched its upgraded doppler radar system called Klystron 9 ...
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 ...
The first operational CPS-9 was installed at Maxwell AFB, Alabama, on 20 June 1954; that radar remained operational for 30 years before finally being replaced on 14 July 1984 by a more modern radar, the AN/FPS-77 (Fuller 1990a). In 1966, the Air Weather Service still had 40 CPS-9s in operation. By 1974, the number was reduced to 11.
Texas leads the nation in the number of severe weather reports at 992 so far in 2023, according to the Storm Prediction Center. The tally includes 42 preliminary tornado reports, 552 large hail ...
By combining a klystron with a TWT, the result is a relatively compact device with improved bandwidth; typical twystrons have bandwidth up to 15% of the design point. The device was developed by Albert La Rue and Rodney Rubert in the early 1960s and was quickly adopted by many radar designs in order to improve frequency agility and thereby ...
The highest temperature ever measured in Texas was 120 °F (48.9 °C), recorded on August 12, 1936 in Seymour, during the 1936 North American Heatwave, and again on June 28, 1994 in Monahans. The lowest temperature ever measured in Texas was −23 °F (−30.6 °C), recorded on February 8, 1933 in Seminole .
[24] [25] For example, dual redundant 12-watt X-band TWTAs are mounted on the body under the dish of the New Horizons spacecraft, [26] which visited Pluto in 2015, then Kuiper belt object 486958 Arrokoth in 2019 to return data at a distance of 43.4 AU from the Sun. Launched in 2021, James Webb Space Telescope makes use of K a-band TWTs.
