Tropospheric and Stratospheric Ozone and Water Vapor Measurements |
||
|
Both long-term and intensive campaign programs for measuring the vertical profile of ozone in the atmosphere with regular weekly balloon soundings are in progress at Boulder, CO; Hilo, HI; South Pole; Trinidad Head, CA; American Samoa; and Suva, Fiji. We also participate in intensive campaigns of daily soundings over 1- to 2-month periods. The most recent Arctic Intensive Ozonesonde Study (ARCIONS) focused on ozone transport and satellite validation. Long-term stratospheric measurements focus on documenting and understanding the effect of human and natural perturbations to the ozone distribution. In the troposphere, emphasis is placed on long-term changes in ozone, which may affect climate and the oxidizing capability of the atmosphere. Over the North Atlantic, profile measurements focus on the effect of the surrounding continental source regions and the role of transport on the ozone distribution throughout the troposphere. We also use balloon-borne instruments to study long-term changes in water vapor in the upper troposphere and lower stratosphere, and to understand the important sources and sinks of this radiatively and chemically important trace gas in the stratosphere. Regular measurements take place in Boulder, Colorado, while special field studies focus on the polar regions (both the Arctic and Antarctic) and the tropics. |
