Overview







Watch a webinar explaining how to navigate the new website





AviationWeather.gov has a new look! Some of the goals of the new website design were to provide a consistent page layout throughout, reduce duplication and limit the number of pages, and achieve mobile responsiveness. The website is organized by utilizing the main page to branch to an interactive map called the Graphical Forecasts for Aviation (GFA), various impacts dashboards, a data and imagery page, and a handful of other pages that provide weather information for the world airspace system. Check out the webinar tutorial video to the left to get a full overview of the website.



Main Page

The main page utilizes the template visible on all pages of AviationWeather.gov. A header at the top guides the user through the website, and a footer at the bottom provides links to USA.gov and NOAA pages. There is a "Top News" bar along the top to provide details on any new updates to the website or important information for the user. The large static image in the center of the screen shows current aviation weather conditions utilizing AWC products. The smaller images provide links to additional data or tools within AviationWeather.gov. Get the latest station data by entering an airport identifier at the bottom.

A

Area Forecast (FA) — Forecast of Visual Flight Rules (VFR) clouds and weather conditions over an area as large as the size of several states, used in conjunction with AIRMETs. FAs over CONUS were discontinued and replaced with the GFA.

Area Forecast Discussion (AFD) — Narrative forecast informational discussion issued by local NWS Weather Forecast Offices.

AIREP — Reports of actual weather conditions encountered by aircraft, typically automated. See also PIREP.

AIRMET (Airmen's Meteorological Information) — Weather advisories of weather that may be hazardous to aircraft, but are less severe than SIGMETs, that depict conditions over a six hour period with a twelve hour outlook. AIRMETs over CONUS have been replaced by G-AIRMETs.

Alaska Aviation Weather Unit (AAWU) — MWO responsible for Alaskan airspace. Website.

Altimeter setting — Station pressure (the barometric pressure at the location the reading is taken) which has been corrected for the height of the station above sea level.

Application Programming Interface (API) — Machine-to-machine data access interface.

Automated Surface Observing System (ASOS) — Weather reporting system which provides surface observations via digitized voice broadcasts and printed reports. Maintained by NWS, FAA, and the Department of Defense.

Automated Weather Observing System (AWOS) — Automated weather reporting system consisting of various sensors, a processor, a computer-generated voice subsystem, and a transmitter to broadcast weather data. Generally AWOS are maintained by the local airport authority, do not report all of the same elements as ASOS, and may not have the same level of backup sensors or maintenance response levels.

Aviation Weather Center (AWC) — National center that issues warnings, forecasts, and analyses of hazardous weather for aviation. More information.

Aviation Weather Testbed (AWT) — A research entity of the Aviation Weather Center comprised of a collaborative team of developers and researchers dedicated to leading the forefront of innovative meteorological techniques for aviation forecasting. Their efforts ensure the protection of pilots and passengers, support of operations, and constant improvement of the forecasting process.

B

Beam blockage — Radar phenomenon that occurs when the radar beam is blocked by terrain and is particularly predominant in mountainous terrain.

BECMG — Gradual change in TAF forecast conditions over longer period, usually two hours.

C

Ceiling — The height above the earth’s surface of the lowest layer of clouds, which is reported as broken or overcast, or the vertical visibility into an obscuration.

Center Weather Advisory (CWA) — Aviation weather advisory for conditions meeting or approaching national in-flight advisory (AIRMET, SIGMET or SIGMET for convection) criteria. More information.

Center Weather Service Unit (CWSU) — Weather offices that provide weather forecasts and advisories to the 21 Air Route Traffic Control Centers (ARTCCs). More information.

Clear air turbulence (CAT) — Turbulence occurring in cloudless regions that causes buffeting of aircraft.

D

Dewpoint — A measure of atmospheric moisture. It is the temperature to which air must be cooled in order to reach saturation (assuming air pressure and moisture content are constant). A higher dew point indicates more moisture present in the air.

Density altitude — Pressure altitude corrected for variations from standard temperature. When conditions are standard, pressure altitude and density altitude are the same. If the temperature is above standard, the density altitude is higher than pressure altitude. If the temperature is below standard, the density altitude is lower than pressure altitude.
