The ongoing Global Atmospheric Measurements Experiment on Tropospheric Aerosols and Gases (Gametag) is beginning to produce some unexpected results. One result is the observation that ozone levels differ greatly at different heights and locations over the Pacific Ocean. Another is that carbon monoxide concentrations in the troposphere do not change as much from the northern to the southern hemisphere as had been suspected from earlier measurements.
Gametag, a cooperative effort among nine institutions, has now completed two series of observational flights aimed at acquiring a detailed accurate picture of the global distribution of many gases. Data processing from the second Gametag flight should be completed by the end of the year.
