METAR (METeorological Aerodrome Report), known as an Aviation Routine
Weather Report, is the standard format for current weather observations.
METARs are generally updated hourly, but some site are more frequent. Special
updates are done as conditions warrant. METARs typically contain information
about the temperature, dew point, wind, precipitation, cloud cover, cloud
heights, visibility, and barometric pressure. They can also contain information
on precipitation amounts, lightning, and other critical data. METARs are shown
as colored flags at airports that provide them.
