Visual METAR presentation for various regions around the world.
|Low Instrument Flight Rules
LIFR* (magenta sky symbol)
|below 500 feet AGL||and/or||less than 1 mile|
|Instrument Flight Rules
IFR (red sky symbol)
|500 to below 1,000 feet AGL||and/or||1 mile to less than 3 miles|
|Marginal Visual Flight Rules
MVFR (blue sky symbol)
|1,000 to 3,000 feet AGL||and/or||3 to 5 miles|
|Visual Flight Rules
VFR+ (green sky symbol)
|greater than 3,000 feet AGL||and||greater than 5 miles|
|*By definition, IFR is ceiling less
than 1,000 feet AGL and/or visibility less
than 3 miles while LIFR is a sub-category of IFR.
+By definition, VFR is ceiling greater than or equal to 3,000 feet AGL and visibility greater than or equal to 5 miles while MVFR is a sub-category of VFR.
|Cloud information not reported|
|Clear sky, reported by automated stations|
|Sky clear, reported by human observer|
|Few clouds, 1-2/8|
|Scattered clouds, 3-4/8|
|Broken clouds, 5-7/8|
|Overcast, 8/8 (i.e. full cloud coverage)|
|The sky is obscured which is the case when a METAR reports vertical visibility and no cloud information|
Note: CAVOK and NSC are mapped to SKC (sky clear).
