METAR is a format for reporting weather information. A METAR weather report is predominantly used by aircraft pilots, and by meteorologists, who use aggregated METAR information to assist in weather forecasting. Raw METAR is the most common format in the world for the transmission of observational weather data.
The X value identifies the Class of the descriptor (i.e. Horizontal Coordinate parameters, Temperature parameters, etc.). The Y value is the descriptor's number within its class. Element descriptors classes 1 through 9 have the special property of remaining in effect from the moment they appear throughout the remainder of the BUFR template ...
In meteorology and aviation, terminal aerodrome forecast (TAF) is a format for reporting weather forecast information, [1] particularly as it relates to aviation. TAFs complement and use similar encoding to METAR reports. They are produced by a human forecaster based on the ground.
ICAO Meteorological Information Exchange Model (IWXXM) is a format for reporting weather information in XML/GML.IWXXM includes XML/GML-based representations for products standardized in International Civil Aviation Organization (ICAO) Annex III, such as METAR/SPECI, TAF, SIGMET, AIRMET, Tropical Cyclone Advisory (TCA), Volcanic Ash Advisory (VAA), [1] Space Weather Advisory and World Area ...
Surface weather observations can include the following elements: The Station Identifier, or Location identifier, consists of four characters for METAR observations, [13] with the first representing the region of the world the station lies within. For example, the first letter for areas in and around the Pacific Ocean is P, and for Europe is E.
The AWOS-C is the most up-to-date FAA owned AWOS facility and can generate METAR/SPECI formatted aviation weather reports. The AWOS-C is functionally equivalent to the ASOS. [4] FAA owned AWOS-C units in Alaska are typically classified as AWOS-C IIIP units while all other AWOS-C units are typically classified as AWOS III P/T units. [5]
The Weather Information Exchange Model (WXXM) is designed to enable the management and distribution of weather data in digital format (XML). WXXM version 2.0, set to be finalized in 2014, is based on Geography Markup Language (GML) and is one of the GML Application Schemas.
SYNOP (surface synoptic observations) is a numerical code (called FM-12 by WMO) used for reporting weather observations made by staffed and automated weather stations. SYNOP reports are typically sent every six hours by Deutscher Wetterdienst on shortwave and low frequency using RTTY .
