Abstract : Per cent deviations of air density from the ARDC Model Atmosphere 1956 are presented for the following locations: Grand Bahama Island, West Indies; Patrick AFB, Florida; Tokyo-Haneda, Japan; International Falls, Minnesota; and Fairbanks, Alaska. Since frequency distributions of air density are often not normal, a mere presentation of formally computed statistics, such as, means and standard deviations has been omitted. Rather the levels of 0.15 per cent, 50 per cent, and 99.85 per cent cumulative percentage frequency were selected to represent median and 'extreme' conditions. The latitudinal and seasonal variations of air density in the different altitude layers are discussed. A separate section has been added under the heading 'Conclusions' to provide a summary of the essential findings. (Author)
