Airports with a TDWR in the US. Another in San Juan, Puerto Rico, is not shown on this map.. Terminal Doppler Weather Radar (TDWR) is a Doppler weather radar system with a three-dimensional "pencil beam" used primarily for the detection of hazardous wind shear conditions, precipitation, and winds aloft on and near major airports situated in climates with great exposure to thunderstorms in the ...
Punta Borinquén Radar Station is a facility of the Puerto Rico Air National Guard home for the 141st Air Control Squadron. Located adjacent to Rafael Hernández Airport (which operates at the old Ramey Air Force Base ), in Aguadilla, Puerto Rico .
Aircraft Meteorological Data Relay (AMDAR) is a program initiated by the World Meteorological Organization. AMDAR is used to collect meteorological data worldwide by using commercial aircraft . Data is collected by the aircraft navigation systems and the onboard standard temperature and static pressure probes.
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 ...
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 addition, a short period forecast called a TREND may be added at the end of the METAR covering likely changes in weather conditions in the two hours following the observation. These are in the same format as a Terminal Aerodrome Forecast (TAF). The complement to METARs, reporting forecast weather rather than current weather, are TAFs.
A pilot report or PIREP is a report of actual flight or ground conditions encountered by an aircraft. Reports commonly include information about atmospheric conditions (like temperature , icing , turbulence ) or airport conditions (like runway condition codes or ground equipment failures).
051730Z indicates that the report was issued on the 5th of the month at 1730 UTC (also known as Zulu, hence the Z). 0518/0624 indicates that the report is valid from the 5th at 1800 UTC until the 6th at 2400 UTC. The remainder of the first line contain the initial forecast conditions. Variations of the codes used for various weather conditions ...
