The Radar Operations Center (ROC) is a National Weather Service (NWS) unit that coordinates the development, maintenance, and training for the NEXRAD weather radar network. [1]
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 Radar Operations Center (ROC) works very closely with the wind farm developers, NOAA National Weather Service Weather Forecast Offices, and their sponsors to help everyone involved understand ...
The WSR-88D Doppler weather radar system, also called NEXRAD, was developed by the National Weather Service during the mid-1980s, and fully deployed throughout the majority of the United States by 1997. There are 158 such radar sites in operation in the U.S., its various territorial possessions and selected overseas locations. This technology ...
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.
Dual-polarized (dual-pol) radar technology is truly a NOAA-wide accomplishment. NSSL spent nearly 30 years researching and developing the technology. The National Weather Service (NWS) and NSSL developed the specifications for the modification, which was tested by engineers at the NWS Radar Operations Center.
In the summer of 1989, this training group, called the Operations Training Facility (OTF) was staffed with six meteorologist instructors and a secretary (referred to as the NEXRAD Training Unit, or NTU). This facility was originally part of the NWS Forecast Office in Norman, OK and administered by the Southern Region of the NWS.
The first weather radar in Idaho, WSR-88D, was installed in Boise, just south of the airport, on September 23, 1993 and officially commissioned on January 11, 1995. This was the 47th Doppler weather radar installed in a new national network known as "NEXRAD".
