Weather compressed into one line.
Also known as: Aviation routine weather report, Aerodrome weather code
The international code reporting observed aerodrome weather as a fixed sequence of groups.
Reports observed weather at an aerodrome in a fixed sequence of coded groups.
Contexts: Technical drawing, Public information
Position in the sequence identifies each group, so a reader knows what a number means from where it sits rather than from a label — which is what makes the report short enough to transmit and read aloud.
Contexts: Technical drawing, Public information
Deliberately language-independent: a pilot in any country reads the same code, which is why it survived the arrival of plain-language weather services rather than being replaced by them.
Contexts: Technical drawing, Public information
A single line of letter and digit groups in fixed order: station, time, wind, visibility, weather, cloud, temperature and pressure, each group's position naming what it is.
