Development and Evaluation of a Size-Resolved Model of Carbonaceous and Mineral Dust Aerosols

该项目将在现有的大气环流模式(GCM)中纳入一个复杂的气溶胶模式，目的是提高GCM预测气溶胶对气候变化的间接影响的能力。气溶胶模式将包括所有主要气溶胶类型(硫酸盐、海盐、碳质和矿物气溶胶)及其微观物理的尺寸分辨表示。该模式将“推动”NCEP对气象场的再分析。模型结果将与实地活动的数据进行比较，例如ACE-2(气溶胶特性实验)。该项目的更广泛影响将是帮助减少当前全球气溶胶模型预测和观测之间的差异。这笔助学金将用于培养一名研究生。

This project will incorporate a sophisticated aerosol model within an existing general circulation model (GCM) with the goal of improving the ability of GCMs to predict the indirect effects of aerosols on climate change. The aerosol model will include size-resolved representation of all major aerosol types (sulfate, sea salt, carbonaceous, and mineral aerosols) and their microphysics. The model will be "nudged" towards NCEP reanalysis of meteorological fields. Model results will be compared with data from field campaigns, such as ACE-2 (Aerosol Characterization Experiment). The broader impacts of this project will be to help reduce discrepancies between current global aerosol model predictions and observations. This grant will provide for the training of a graduate student.
