Clouds and Weather
Cloud height sensors reach about 12,000 feet above the ground. At major airports, this information can be augmented by a trained observer.
This can sometimes mean that conditions are clear, when a cloud base is above 12,000 feet.
Decoding Cloud Information:
Up to 3 layers (the lowest 3 layers) of clouds can be reported.
The first 3 letters of a cloud group describe the amount of sky coverage. The last 3 numbers indicate the base of that layer, above the ground x 100 feet.
SKC: Sky Clear.
CLR: No clouds below 12,000 feet above ground level, as detected by automatic equipment.
FEW: Few Clouds - Between 1/8 and 2/8 of the sky is covered by clouds.
SCT: Scattered Clouds - Between 3/8 and 4/8 of the sky is covered by clouds.
BKN: Broken Clouds - Between 5/8 and 7/8 of the sky is covered by clouds.
OVC: Overcast - 8/8 of the sky is covered by clouds.
VV: Vertical Visibility - An indefinite cloud ceiling caused by fog, rain, snow, etc.
