Effect of Future Climate Change on Stratosphere-to-Troposphere-Exchange Driven Ozone in the Northern Hemisphere.

ABSTRACT: Future estimates of atmospheric pollutant concentrations serve as critical information for policy makers to formulate current policy indicators to achieve future targets. Tropospheric burden of O₃ is modulated not only by anthropogenic and natural precursor emissions, but also by the downward transport of O₃ associated with stratosphere to troposphere exchange (STE). Hence changes in the estimates of STE and its contributions are key to understand the nature and intensity of future ground level O₃ concentrations. The difference in simulated O₃ mixing ratios with and without the O₃-Potential Vorticity (PV) parameterization scheme is used to represent the model estimated influence of STE on tropospheric O₃ distributions.
