项目摘要
This Research in Undergraduate Institutions (RUI) project, co-funded by the Atmospheric Chemistry Program and the Environmental Chemical Science Program, is focused on laboratory experiments to measure important physical and chemical properties of selected chemical species that mimic the behavior of small particles and aerosol found in atmosphere. These properties are important for modeling cloud and ice formation and are needed for improving weather and climate models.Measurements are being made of the temperature dependent solubilities and glass transition temperatures as a function of concentration for aqueous organic acid/metals/ammonium sulfate solutions that contain solutes relevant for understanding the behavior of upper tropospheric aerosols. Properties of glassy organic acid salts and their mixtures with ammonium sulfate are of special interest because recent research suggests that glassy organic aerosol particles are effective at forming ice nuclei. The results of this effort will be used in climate models to make better predictions of how clouds and ice in the atmosphere influence climate.
这项本科院校研究 (RUI) 项目由大气化学项目和环境化学科学项目共同资助,重点是实验室实验,以测量模拟大气中小颗粒和气溶胶行为的选定化学物质的重要物理和化学性质。这些特性对于模拟云和冰的形成非常重要,并且是改进天气和气候模型所必需的。正在测量有机酸/金属/硫酸铵水溶液的温度依赖性溶解度和玻璃化转变温度作为浓度的函数,这些溶液含有与了解对流层上层气溶胶行为相关的溶质。玻璃状有机酸盐及其与硫酸铵的混合物的性质特别令人感兴趣,因为最近的研究表明玻璃状有机气溶胶颗粒可有效形成冰核。这项工作的结果将用于气候模型,以更好地预测大气中的云和冰如何影响气候。
