N Summary from the United States Air Force

Dataset Identification:

Resource Abstract:
N Summaries are means and percentage frequency tabulations for stations around the world. There are approximately 2674 worldwide stations with five or more years data for which the N Summary was prepared. The summaries were calculated using surface weather observations collated by the United States Air Force. The parameters in an N Summary are one or more of the following monthly, seasonal, and annual tabulations: 1. Percentage frequency of surface winds (kts) by day, hour and month, to 16 points of the compass, 2. Percentage frequency of surface winds (kts) (seasonal and annual) to 16 points of the compass, 3. Precipitation amounts (in.), 4. Mean frequency of daily maximum temperature (Deg. F), mean maximum, and extreme maximum temperature (Deg. F), 5. Mean frequency of daily minimum temperature (Deg. F), mean minimum and extreme minimum temperature (Deg. F), and mean daily temperature range (Deg. F), 6. Mean number of days favorable for indicated military operations, 7. Miscellaneous data; mean number of days of occurrence of various weather phenomena, 8. Mean number of days with indicated total and low cloud amounts (oktas), 9. Percentage frequency of observations with low clouds (amount in 8ths, height in feet) and visibility (miles) reported, 10. Relative humidity means, 11. Percentage frequency distribution of wind speed (kts) and temperature (Deg. F), 12. Percentage frequency of visibility (miles) and various atmospheric phenomena, 13. Mean number of days with specified phenomena, 14. Mean cloudiness (%), 15. Snow depth (in.), 16. Percentage frequency of surface winds (kts) to 8 points of the compass (monthly), 17. Percentage frequency of surface winds (kts) to 8 points of the compass/ seasonal, 18. Sea level pressure (mb), means, and standard deviations. Some of the tabulations are for all hours of the day while others may be for each 3-hourly, 6-hourly, or 12-hourly segment of the day, and in some cases, for only one observation a day.
