Aviation Routine Weather Report (METAR)
A METAR is a weather report for a specific place and time, encoded in a standardized format.
METARs include:
- Day of the month and zulu time of observation
- Wind (given relative to true north)
- Visibility
- Cloud cover (ceilings given in AGL)
- Temperature and dewpoint
- Altimeter
- Remarks
METARs are published hourly, however if conditions change rapidly, a SPECI report may be issued.
