Latitudinal and Vertical Relationship between Tropospheric Ozone and Water Vapor as Measured in Project Gametag.
Abstract
Reported are the O3 and dewpoint data recorded during the 1977 and 1978 GAMETAG field experiments. These data are primarily those recorded aboard an aircraft during horizontal flight legs at altitudes between 5-6.5 kilometers (free troposphere) and below one kilometer (boundary layer). The total latitude range covered was 70 N to 58 N and involved flight operations over Canada, Alaska, the eastern and central north Pacific, and the central and western south Pacific. A comparison of the GAMETAG ozone and dewpoint data shows a significant negative correlation between O3 and dewpoint; or if the comparison is made with dewpoint depression, a significant positive correlation. The strongest negative correlation between O3 and dewpoint appears at those latitudes showing the highest ozone variability. This negative correlation when coupled with the presence of ozone layering implies that a major source of the ozone observed during the GAMETAG flights was that resulting from the downward sloping transport of ozone rich upper tropospheric or lower stratospheric air.
