项目摘要

This is a pilot study to investigate the chemistry occurring within clouds that can lead to the formation of secondary organic aerosol in the atmosphere. It is expected that chemical reactions taking place within fog and cloud droplets are responsible for much of the differences in the predicted and measured mass of atmospheric organic aerosol. The results of the project will lead to a better understanding of how clouds can affect air quality. The primary hypothesis of the study is that organic compounds within cloud-processed aerosols will be more soluble as a result of oxidation reactions and that cloud droplet residuals (the aerosols remaining after cloud droplets evaporate) will be higher in organic mass than aerosols being drawn into clouds from below the cloud-base. The results of this study will lead to improved modeling of the heterogeneous chemical processing of organics within clouds.
这是一项试点研究,旨在调查云内发生的化学反应,这些化学反应可能导致大气中二次有机气溶胶的形成。 预计雾和云滴内发生的化学反应是造成大气有机气溶胶预测质量和测量质量差异的主要原因。 该项目的结果将有助于更好地了解云如何影响空气质量。这项研究的主要假设是,经过云处理的气溶胶中的有机化合物由于氧化反应而更易溶解,并且云滴残留物(云滴蒸发后残留的气溶胶)的有机质量将高于从云底以下吸入云中的气溶胶。这项研究的结果将导致改进的模拟云内的有机物的非均相化学处理。
