This project is an analysis of the separate contributions of greenhouse gases and tropospheric aerosols to the surface energy budget, including feedbacks associated with the hydrological cycle. The raw materials for the project are data on surface radiation and weather parameters from global and regional observing stations. The data will be used to test some of the current ideas about the positive and negative feedbacks associated with aerosols and changes in aerosol deposition rates. This work will be a step in the complicated but very important problem of determining the role aerosols play in climate, one of the major sources of uncertainty in the assessment of anthropogenic trends in climate variations.

该项目分析温室气体和对流层气溶胶对地表能量收支的单独贡献，包括与水文循环有关的反馈。 该项目的原始材料是来自全球和区域观测站的地面辐射和天气参数数据。 这些数据将被用来测试一些目前的想法与气溶胶和气溶胶沉积速率的变化相关的正反馈和负反馈。 这项工作将是在确定气溶胶在气候中的作用这一复杂但非常重要的问题上迈出的一步，气溶胶在气候变化中的作用是评估人为趋势的不确定性的主要来源之一。
