Combined Impact of Aerosol Plus Greenhouse Gas Forcing on Surface Energy Budget and Water Cycle on a Multi-decadal Timescale

该项目分析了温室气体和对流层气溶胶对地表能量收支的不同贡献，包括与水文循环有关的反馈。该项目的原材料是来自全球和区域观测站的地表辐射和天气参数数据。这些数据将被用来检验目前关于气溶胶的正反馈和负反馈以及气溶胶沉积率变化的一些想法。这项工作将是确定气溶胶在气候中的作用这一复杂但非常重要的问题的一步，这是评估气候变化中人为趋势的主要不确定性来源之一。

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.
