Organic Composition of Fogs and Clouds

该项目正在开发研究云和雾的有机成分以及云和雾吸收含碳气溶胶粒子的效率的方法。 该项目包括一项实验室开发工作，以提高测量云和雾滴中疑似存在的各种有机物种浓度的能力，以及一系列实地实验，以收集适合应用已开发的有机分析技术套件的样本。 实地活动被用来收集样本的云/雾类型是季节性的重要在三个不同的环境：冬季辐射雾在加州的中央谷，春季层云拦截南部加州沿海丘陵，夏季地形云拦截落基山脉的西坡。

This project is developing methods for studying the organic composition of clouds and fogs and the efficiency with which clouds and fogs scavenge carbonaceous aerosol particles. The project includes a laboratory development effort to improve capabilities for measuring concentrations of the diverse organic species suspected to be present in cloud and fog drops and a series of field experiments to collect samples suitable for application of the developed suite of organic analytical techniques. The field campaigns are being used to collect samples of cloud/fog types that are seasonally important in three distinct environments: winter radiation fogs in the California's Central Valley, spring stratus clouds intercepting the coastal hills of Southern California, and summer orographic clouds intercepting the western slope of the Rocky Mountains.
