The Citizen Weather Observer Program is a program to collect surface weather observations from thousands of privately operated weather stations, into the FindU database, and forward it to the Meteorological Assimilation Data Ingest System (MADIS Archived 2009-03-12 at the Wayback Machine), operated by the National Oceanic and Atmospheric Administration (NOAA).
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.
TAFs are issued at least four times a day, every six hours, for major civil airfields: 0000, 0600, 1200 and 1800 UTC, [4] and generally apply to a 24- or 30-hour period, and an area within approximately five statute miles (8.0 km) (or 5 nautical miles (9.3 km) in Canada) from the center of an airport runway complex. TAFs are issued every three ...
A typical METAR contains data for the airport identifier, time of observation, wind direction and speed, visibility, current weather phenomena such as precipitation, cloud cover and heights, temperature, dew point, and barometric pressure. This information forms the body of the report, consisting a maximum of 11 groups of information.
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 ...
TAMDAR (Tropospheric Airborne Meteorological Data Reporting) [1] is a weather monitoring system that consists of an in situ atmospheric sensor mounted on commercial aircraft for data gathering. It collects information similar to that collected by radiosondes carried aloft by weather balloons .
In aviation meteorology, a trend type forecast (TTF), also known simply as a trend, is a weather forecast written by a person on location at a major airport or military base. A TTF is a professionally considered forecast for weather over a two-hour period, [ 1 ] and is based on an actual weather report, such as a METAR or SPECI and appended to ...
ROFOR is an abbreviation for "Route Forecast". [1] As the name suggests is the weather forecast of the route of any aircraft which will be flying through the route. ROFOR contains various information regarding date and time of forecast, direction and speed of the wind, aerodrome ICAO code for which the forecast is made, cloud levels and ...
