9408941 Hobbs With this award, Dr. Hobbs will attempt to quantify the effects of aerosols on climate through their effects on clouds through a series of airborne observations. Measurements will be obtained of key parameters for a variety of aerosols, for various cloud types, and in several climatological regimes. The measurements include cloud condensation nucleus (CCN) efficiencies (i.e., the number of CCN produced by unit mass of a chemical species) of various types of atmospheric aerosols, the effects of these aerosols on cloud droplet concentrations and size distributions and the radiative properties of clouds (particularly near cloud tops). The measurements will be made in strongly polluted air in the northeastern United States, in the smoke produced by biomass burning in the Amazon Basin, and in moderately polluted as well as quite clear air in the Pacific Northwest and Alaska. This project will contribute to a better understanding of climate processes and the potential for global climate change. It is being funded under the Role of Clouds, Energy, and Water in Global Climate Change Research Opportunity. ***

小行星9408941 有了这个奖项，霍布斯博士将试图量化气溶胶对气候的影响，通过他们对云的影响，通过一系列的空中观测。 将获得各种气溶胶、各种云类型和几种气候状况的关键参数的测量结果。 测量结果包括云凝结核（CCN）效率（即，各种类型大气气溶胶的化学物质单位质量产生的CCN数量）、这些气溶胶对云滴浓度和粒径分布的影响以及云的辐射特性（特别是云顶附近）。 这些测量将在美国东北部严重污染的空气中进行，在亚马逊盆地生物质燃烧产生的烟雾中进行，以及在太平洋西北部和阿拉斯加的中度污染和相当清澈的空气中进行。 该项目将有助于更好地了解气候过程和全球气候变化的潜力。 该项目由云、能源和水在全球气候变化研究机会中的作用资助。 ***
