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 ...
WXXM 1.0 was introduced in 2007, representing METAR, SPECI, TAF, SIGMET and other ICAO information as specified in International Civil Aviation Organization (ICAO) Annex III. WXXM 1.1 [1] was released in 2010 with a number of additional products beyond ICAO Annex 3. WXXM 2.0 was released in 2014 as a major update.
ASOS sensors, located at Salinas, California. Surface weather observations have traditionally been taken at airports due to safety concerns during takeoffs and landings. The ICAO defines the International Standard Atmosphere (also known as ICAO Standard Atmosphere), which is the model of the standard variation of pressure, temperature, density, and viscosity with elevation/altitude in the ...
This can be in the form of statistical techniques to remove known biases in the model, or of adjustment to take into account consensus among other numerical weather forecasts. [59] MOS or model output statistics is a technique used to interpret numerical model output and produce site-specific guidance.
Furthermore, even what is reported in the main body of the METAR (the element containing something along the lines of 06/M02) is incorrect 2 times out of 15—for example, if the actual temperature were 41.72 °F, it gets measured as 42 °F and converted to 6 °C in the main body of the METAR, but actually 41.72 °F = 5.40 °C and should round ...
Brussels Airport (Dutch: Luchthaven Brussel, French: Aéroport de Bruxelles) (IATA: BRU, ICAO: EBBR) is the main international airport of Belgium. It is located in the municipality of Zaventem in Flemish Brabant , 12 kilometres (7.5 mi) northeast [ 2 ] of Brussels .
