Access to the summary code forms used for aeronautical meteorology, as established by ICAO. On each page a code is explained: the code is presented on the front of the page and the examples and the tables are shown on the back. Some codes are used for aerodrome meteorology (METAR, TREND, TAF) and others for wider areas (FIR, UIR, low-level flights) of the airspace (GAMET, AIRMET, SIGMET).

For a more detailed explanation see the MET Guide.
