Improved Methods for Modeling the Atmospheric Aerosol Size and Composition Distribution for Regional-to-Global Climate Change Applications

题目：区域到全球气候变化应用中大气气溶胶大小和成分分布模拟的改进方法。本提案是对目前广泛使用的综合空气污染评估EPA模型进行修改。这些修改是将模型应用于气候变化问题的正确方向上的必要步骤。在提出的工作中，试图对目前的模态气溶胶动力学进行推广，以允许多于通常的两种模态，允许模态的产生和破坏具有更大的普遍性，并允许具有大小依赖组成的多组分系统。从长远来看，这项研究提高了评估区域环境影响的社会能力。

ABSTRACT ATM- 9711488 Shankar, Uma Microelectronics Center of North Carolina TITLE: Improved Methods for Modeling the Atmospheric Aerosol Size and Composition Distribution for Regional to Global Climate Change Applications. This proposal is for modification of an integrated air pollution assessment EPA model widely in use. These modifications are necessary steps in the right direction to apply the models for climate change issues. The generalization of the present modal aerosol dynamics to allow for more than usual two modes, to allow more generality in creation and destruction of modes, and to allow for multi-component systems with size dependent composition, is attempted in the work proposed. This research enhances in the long run societal abilities at estimating regional environmental impacts.
