THEREFORE, THE 10 MILE VISIBILITY COLUMN SOMETIMES CONTAIN SMALL PERCENTAGE VALUES. HOWEVER. THESE VALUES ARE OF LITTLE MEANING AND SHOULD BE DISREGARDED. FOR METAR CIVILIAN STATIONS REPORTING "CAVOK", ALL CEILINGS ABOVE 5000 FEET WERE SUPPESSED TO SOCO FEET. THEREFORE, NO PERCENT VALUES APPEAR ABOVE 5000 FEET.
