Mixing State of Aerosols and Its Impact on Global/Urban Climate and Urban Ozone

该项目的目标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。这项工作包括发展全球尺度的基线气溶胶模式模拟，并与实际观测和气候学进行比较。该项目将研究全球和区域尺度的气溶胶颗粒混合状态，以及由此产生的直接辐射强迫和气溶胶颗粒对气候的反馈。待调查的气溶胶包括(a)化石燃料烟尘和有机物，(b)生物质燃烧气体和颗粒，(c)二氧化硫和由此产生的硫酸盐。

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.
