COMPARISON OF OZONE MEASUREMENT TECHNIQUES USING AIRCRAFT, BALLOON, AND GROUND-BASED MEASUREMENTS

摘要

In order to verify the ultraviolet absorption technique used in the Global Atmospheric Sampling Program, two flight experiments were conducted employing several techniques, both in situ and remote, for measuring atmospheric ozone. The first experiment used the NASA CV-990 equipped with an ultraviolet absorption ozone monitor and an ultraviolet spectrophotometer, a balloon ozonesonde, and a Dobson station for determining and comparing the ozone concentra¬tion data. A second experiment compared ozone data from an automated sampling system aboard a B-747 with data from a manned system installed on the NASA CV-990 during a cross¬country flight with both aircraft following the same flight path separated by 32 kilometers.
