The goal of this project will be to analyze the effect of the mixing state of aerosols on global and regional direct forcing and temperatures. This effort involves the development of global-scale baseline aerosol model simulations and comparison with actual observations and climatologies. The project will investigate the global- and regional-scale mixing state of aerosol-particles and the resulting direct radiative forcing and feedbacks of aerosol-particles to climate. Aerosols to be investigated include (a) fossil-fuel soot and organic matter, (b) biomass burning gases and particles, (c) sulfur dioxide and resulting sulfate.

该项目的目的是分析气溶胶混合状态对全球和区域直接强迫和温度的影响。这项工作涉及全球规模的基线气溶胶模型模拟的开发以及与实际观察和气候的比较。该项目将研究气溶胶颗粒的全球和区域尺度混合状态，以及由此产生的直接辐射强迫和气溶胶粒子的反馈到气候。要研究的气溶胶包括（a）化石燃料烟灰和有机物，（b）生物质燃烧气体和颗粒，（c）二氧化硫和产生的硫酸盐。
