CEILING WLSUS vISIBILITY AND SKY COVER SUMMARIES

CEILING VERSUS VISIBILITY SUMMARY

THIS SUMMARY IS A BIRVARIATE FREOUENCV DISTRIBUTION BY CLASSES Or CEILING FROM "C" THROUGH EQUAL

To OR GREATER THAN 20,000 FEET AND AS A SEPARATE CLASS "NO CEILING". VERSUS VISIBILITY IN 16CLASSES FROM ZERO THROUGH EQUAL 10 OR GREATER THAN 10 PILES.

DATA VERIVEO FROM HOURLY OBSERVATIONS.

FREQUENCY DISTRIBUTION PRESENTED BY TIE STANDARD 3-HOUR TIME GROUPS BY MONTH. MONTHLY AND ANNUALLY IALL YEARS

COMBINEDI.

NOTES:

BEGINNING IN 19b&, MLTAR STATIoN1

REPORTED VISIBILITIES TO 6 MILLS AND GREATER THAN

6 MILES. THEREFORE THE C(LUMN FOR VISIBILITIES EQUAL TO OR GREATER THAN 10 MILESAPPEAR BLANK.

AS A RULE, AIRWAYS STATlOkS NORMALLY REPORT VISIBILITIES TO b MILES AND 7 OR GREATER, HOWEVERSOME STATIONS REPORT HIGHER VALUES. THEREFORE. ThE 10 MILE VISIBILLTY COLUMN SOMETIMES CONTAINSMALL PERCENTAGE VALUES. HOWEVER, THESE vALUES ARE OF LITTLE MEANING AND SHOULD BE

DISREGARDED.

FOR METAR CIVILIAN STATIOlS REPORTING "CAVOK", ALL CEILINGS ABOVE 5000 FEET WERE SUPPESSEDTO 5000 FEET. THEREFORE. NO PERCENT VALUES APPEAR ABOWE SOO FEET.

SKY COVER SUMMARY

PRESENTS PERCENTAGES OF SKY COVER IN EITHER IoTHs OF COVERAGE OR "AIRWAYS CLASSIFICATIONS".

DATA SUMMARIZED BY THE STANDARF 3-HOUR TINE GROUPS BY PONTH. MONTHLY AND ANNUALLY (ALL TEARS COMBIVED.

ALSO PRESENTED ARE MEAN SKY COVERS.

FOR AIRWAY STATIONS. THE CONVEYSON FROM THL AIRWAYS DESIGNATIONS TO IOTHS FOR PRESENTATION ARE:

CLEAR 0/10
