Due to extreme northern locations of some of these radars, the physics of radiowave propagation in the 1215–1400 MHz frequency range is even more critical for target detection requirements. The AN/FPS-124 is intended to cover any surveillance gaps left by the North Warning System's long range radar, the AN/FPS-117.
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 ...
Vaca is the Spanish word for cow. Although cattle ranching historically played an important role in the area, Mount Vaca and the nearby city of Vacaville are actually named for Juan Manuel Cabeza Vaca (1782–1856), who with Juan Felipe Pena received in 1843 the Rancho Los Putos Mexican land grant, which included the peak that now bears Vaca's name.
Whipped by powerful winds, trees fell on homes across Northern California, and one crushed a car on Highway 101 near Santa Rosa, injuring a motorist. Peak gusts even exceeded 100 mph at Pablo ...
The mountain is topped by an eight and a half story (84.5 feet tall) concrete radar tower (5 floors interior), known locally as "the Cube" or "the Box". [18] The tower was part of Almaden Air Force Station, a radar surveillance post which operated from 1958 to 1980. [19] The mountain is also the site of the Bay Area NEXRAD weather radar. [20]
As the storm courses through Northern California, rain is in the forecast for Sacramento. McKinley Thompson-Morley walks to work in the rain on Wednesday, Jan. 24, 2024 in downtown Sacramento near ...
A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. [1] It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered the frequency of the returned signal.
A camera system designed to monitor California’s vast terrain for smoke and wildfires captured video on Friday of what is believed to be the first tornado to impact the Lower 48 in 2025.
