Demonstrates the importance of ozone to climate by comparing general circulation model (GCM) simulated present climates between two atmospheric ozone climatologies: a version currently used in the NCAR GCM's (CCM1 and GENESIS) and an updated version. Results suggest that atmospheric ozone is important in simulating the regional climate and observed ozone changes in the last few decades may have played...
Observations during the past few decades indicate that the distribution of atmospheric ozone has been changing, notably decreases in the lower stratosphere around the globe and increases in the upper troposphere in the mid-to-high latitudes of the Northern Hemisphere. These changes can perturb the radiative forcing of the Earth-atmosphere climate system and thus raise the issue of atmospheric ozone...
