Worldwide Airfield Summary

The Worldwide Airfield Summary contains a selection of climatological data produced by the U.S. Air Force, Air Weather Service. The reports were compiled from dozens of domestic and international sources. It consists of summaries for approximately 4,000 airfield stations worldwide and the climatic areas in which they are located, for various periods ending at or before May 1974. A keyed subset (June 1969) is available digitally upon request.

The data presented are monthly and annual summaries of: 1. Absolute maximum and minimum temperatures (Deg. F), 2. Mean daily maximum and minimum temperatures (Deg. F), 3. Mean number of days with maximum temperature equal to or greater than 90 Deg. F, 4. Mean number of days with minimum temperature equal to or less than 32 or 0 Deg. F, 5. Mean dew-point temperature (Deg. F), 6. Mean relative humidity (%), 7. Mean pressure altitude (feet), 8. Mean precipitation (in.), 9. Mean snowfall (in.), 10. Mean number of days with precipitation equal to or greater than 0.1 inch, 11. Mean number of days with snowfall equal to or greater than 1.5 inch, 12. Mean number of days with an occurrence of visibility less than 0.5 mile, 13. Mean number of days with thunderstorms, 14. Percent frequency surface wind speed equal to or greater than 17 knots, 15. Percent frequency surface wind speed equal to or greater than 28 knots, 16. Percent frequency ceiling less than 5,000 feet and/or visibility less than 5 miles, 17. Percent frequency ceiling less than 1,500 feet and/or visibility less than 3 miles by 3-hourly increments, 18. Percent frequency ceiling less than 300 feet and/or visibility less than 1 mile by 3-hourly increments, 19. Mean number of days with ceiling equal to or greater than 1,000 feet and visibility equal to or greater than 3 miles, 20. Mean number of days with ceiling equal to or greater than 2,500 feet and visibility equal to or greater than 3 miles, 21. Mean number of days with ceiling equal to or greater than 6,000 feet and visibility equal to or greater than 3 miles, 22. Mean number of days with ceiling equal to or greater than 10,000 feet and visibility equal to or greater than 3 miles, 23. Mean number of days ceiling equal to or greater than 2,000 feet and visibility equal to or greater than 3 miles with surface wind speed less than 10 knots, 24. Mean number of days with surface wind speed equal to or greater than 17 knots and no precipitation, 25. Mean number of days with surface wind speed 4 to 10 knots and temperature 33 to 89 Deg. F and no precipitation, 26. Mean number of days with sky cover less than 3/10ths and visibility equal to or greater than 3 miles.
