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.

该研究在本科院校（RUI）项目正在研究如何从森林和植物的排放可能会在大气中的小颗粒的表面反应，以改变其光学特性。这些变化可以改变颗粒物吸收或散射太阳辐射的程度，并影响其对气候的影响。本研究在一所大学进行，实验由一组大学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，目的是：（1）测量矿物基质对生物源VOCs的反应性吸收;（2）量化矿物基质对生物源VOCs的影响？大气处理？（3）调查表面吸附的BVOCs的非均相氧化;（4）量化BVOCs对矿物气溶胶的气候相关特性的影响。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型具有一定的参考价值。该项目支持德鲁大学本科生的物理大气化学研究计划，德鲁大学是一所拥有1，600名学生的小型文理学院。
