The abbreviation SKC shall be used at manual In the METAR you will also find the air pressure at the mean sea level (QNH). This is calculated by recalculating the air pressure at terrain height (QFE) back to sea level. Air pressure can be expressed in inches of mercury (preceded by an A) or hectopascals (preceded by a Q). The METAR can report clear skies, and maybe 5 miles of visibility, but in the air, the slant visibility is really low which makes it incredibly difficult to pick out the airport.
