Human activities such as the intensive use of fossil fuel have been imposing significant perturbations to the atmosphere and air quality on the global scale. Tropospheric ozone is important as a greenhouse gas, as a precursor for OH, the ultimate cleansing agent in the atmosphere, and as a surface air pollutant toxic to humans and vegetation. Global change in the coming decades, including climate change and changes in anthropogenic emissions can have potentially large effects on tropospheric ozone, on hemispheric transport of air pollution, and on air quality.
