The PI has used the National Center for Atmospheric Research Community Climate Model version 3, NCAR-CCM3, together with observational analyses to study climate processes important to atmospheric ozone and sulfate aerosols. In collaboration with Dr. Isaksen of the University of Oslo he has examined the chemical aspects of these constituents with the ultimate goal of developing a global climate-chemistry model. Under this renewal award, the PI will continue his effort focusing on the following:(i) the role of atmospheric ozone in affecting present climate;(ii) the effect of climate and climate change on ozone distribution;(iii) diagnoses of the systematic biases of the general circulation model simulated large-scale climate relevant to atmospheric chemistry, as part of the Atmospheric Model Intercomparison Project, AMIP; and(iv) projections of climate change.The work is important as it may provide background information useful for developing policy on emissions targets.

PI使用了国家大气研究中心社区气候模型第3版NCAR-CCM 3，以及观测分析来研究对大气臭氧和硫酸盐气溶胶重要的气候过程。 他与奥斯陆大学的Isaksen博士合作，研究了这些成分的化学方面，最终目标是开发一个全球气候化学模型。 根据该续约合同，PI将继续专注于以下方面： 大气臭氧在影响当前气候方面的作用;（二）气候和气候变化对臭氧分布的影响;（三）作为大气模式相互比较项目的一部分，诊断模拟与大气化学有关的大尺度气候的大气环流模式的系统偏差;以及（iv）气候变化预测。这项工作很重要，因为它可以提供对制定排放目标政策有用的背景信息。
