Following is the general structure of a SYNOP message. The message consists of a sequence of numeric groups, which may also contain slashes (indicating missing data) in addition to numeric digits. Leading numbers are fixed group indicators that indicate the type of observation following, and letters are replaced with numbers giving the weather ...
A BUFR message is composed of six sections, numbered zero through five. Sections 0, 1 and 5 contain static metadata, mostly for message identification. Section 2 is optional; if used, it may contain arbitrary data in any form wished for by the creator of the message (this is only advisable for local use).
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 colour state may be appended to a METAR report. A short period forecast called a TREND which covers the following two hours from the observation may also be added, often with reference to the colour state. [citation needed]
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.
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 the end of it. [1] A TTF is similar to or sometimes in addition to a TAF, a terminal aerodrome forecast, but during the TTF's validity period is considered superior to a TAF.

Pilots may receive this data through a "Snowtam runway state decoder" which forms an appendix to the internationally recognised METAR (METeorological Aerodrome Report). In some countries in Europe, pilots will not receive local updated/modified braking action reports directly from an air traffic control (ATC) source unless a recent braking ...
