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 ...
Wind turbines, due to their height above ground, affect the WSR-88D data in several ways. When the radar beam interacts with the blades of the wind turbines, it causes strong returns that can look ...
The radar is a NEXRAD WSR‐88D, and was one of the first in the nation to be upgraded to dual polarization capability on September 21, 2011. [9] [8] It is the only operational WSR-88D that scans as low as 0.2 degrees above the horizon, which sometimes causes image artifacts due to sea clutter. [10] [11]
In 1996 the WSR-88D radar was completed and joins a network of other "NEXRAD" radars throughout the country, while the WSR-74C in Springfield was officially decommissioned. [2] In 1998 an Advanced Weather Interactive Processing System (AWIPS) is installed at the office and helps forecasters make more accurate weather forecasts in the region.
A tornado warning is issued when a tornado is indicated by the WSR-88D radar or sighted by spotters, NWS says. Therefore, people in the affected area should seek safe shelter immediately. Warnings ...
A NEXRAD weather radar currently used by the National Weather Service (NWS) is a 10 cm wavelength (2700-3000 MHz) radar capable of a complete scan every 4.5 to 10 minutes, depending on the number of angles scanned, and depending on whether or not MESO-SAILS [7] is active, which adds a supplemental low-level scan while completing a volume scan ...
The Joint Polarization Experiment (JPOLE) was a test for evaluating the performance of the WSR-88D in order to modify it to include dual polarization.This program was a joint project of the National Weather Service (NWS), the Federal Aviation Administration (FAA), and the US Air Force Meteorological Agency (AFWA), which took place from 2000-2004.
The current office in Tulsa maintains a WSR-88D (NEXRAD) radar system, and Advanced Weather Interactive Processing System (AWIPS) that greatly improve forecasting in the region. Tulsa is in charge of weather forecasts, warnings and local statements as well as aviation weather and NOAA Weather Radio broadcasts in its service area.
