METARS AND TAFS

  NOTE:  

Atmospheric pressure as reported for METARs is given in hectopascals (hPa), except for in the United 

States, where it is reported in inches of mercury (in Hg).  Temperatures are reported in Celsius.

  NOTE:  

METAR information is only displayed within the installed aviation database service area.

METAR  (METeorological  Aerodrome  Report)  is  the  standard  format  for  pre-flight  weather  briefings.  

METARs are updated hourly and are considered current.  METARs typically contain information about the 

temperature, dewpoint, 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.

TAF (Terminal Aerodrome Report) is the standard format for 24-hour weather forecasts. TAFs may contain 

some  METAR  data,  but  generally  cover  a  smaller  area.    It  typically  forecasts  significant  weather  changes, 

temporary changes, probable changes, and expected changes in weather conditions.

METAR and TAF text are displayed on the Weather Information Page.  METAR data is displayed first in a 

decoded fashion, then as raw text.  TAF information is displayed only in its raw form.
