Index

Infrared Satellite data is available over North America and Europe and depicts 

cloud top temperatures from satellite imagery. Brighter cloud top colors indicate 
cooler temperatures occurring at higher altitudes. Information is updated every 
half hour. 

 

NOTE:  Atmospheric pressure reported for METARs is given in hectopascals 
(hPa), except 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), 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.
