RUI: Reactive Uptake and Heterogeneous Chemistry of Biogenic VOCs on Mineral Aerosol

这个本科院校研究（RUI）项目正在研究森林和植物的排放物如何对大气中小颗粒的表面发生反应，从而改变它们的光学特性。这些变化可以改变粒子吸收或散射太阳辐射的程度，并影响它们对气候的影响。该研究在一所本科院校进行，实验由一组本科生研究人员和一名当地高中科学教师在首席研究员的指导下进行。本研究的目的是：(1)测量生物源性VOCs在矿物基质上的反应性吸收；(2)量化？大气处理?矿物界面对BVOC的吸收；(3)研究表面吸附BVOCs的非均相氧化；(4)量化BVOCs对矿物气溶胶气候相关特性的影响。本研究结果对改进大气中二次有机气溶胶的形成和影响的模式具有重要意义。该项目支持德鲁大学（Drew University）一项针对本科生的物理大气化学研究项目。德鲁大学是一所小型文理学院，拥有1600名学生。

This Research in Undergraduate Institutions (RUI) project is investigating how emissions from forests and plants might react on the surfaces of the small particles in the atmosphere to change their optical properties. These changes can alter the extent to which the particles absorb or scatter solar radiation, and influence their impact on climate. The research takes place at an undergraduate institution and the experiments are being performed by an undergraduate team of researchers and one local high school science teacher under the guidance of the Principal Investigator.The objectives of this research are to: (1) Measure the reactive uptake of biogenic VOCs on mineral substrates; (2) Quantify the impact of ?atmospheric processing? on BVOC uptake by mineral interfaces; (3) Investigate the heterogeneous oxidation of surface adsorbed BVOCs; and (4) Quantify the impact of BVOCs on the climate-relevant properties of mineral aerosol. The results of this research are useful for improving models of the formation and impact of secondary organic aerosol in the atmosphere. This project supports an active research program in physical atmospheric chemistry for undergraduate students at Drew University, a small liberal arts college with 1,600 students.
