This project will improve the understanding of atmospheric chemistry processes over tropical forest ecosystems. A mobile profiling system will be used to characterize emissions and deposition of volatile organic compounds (VOC) over horizontal and vertical scales across different forest sub-types. The data will be collected during a series of drone-enabled experiments conducted in both wet and dry seasons in the Adolfo Ducke Forest Reserve, located on the northern outskirts of Manaus Brazil in central Amazonia. The results will be used to improve atmospheric chemistry modeling and databases that characterize the emissions of biogenic compounds from vegetation.The scientific questions that will be addressed during this project include the following: (1) What is the horizontal heterogeneity in the magnitude and types of VOC emission and deposition for forest landscapes that vary on intermediate scales of 100's m? (2) What is the vertical heterogeneity and diel cycle of reactive VOCs in a turbulent planetary boundary layer? and (3) What is the vertical heterogeneity in the speciation and concentration of semivolatile organic compounds (SVOC) produced as photochemical reaction products of VOC oxidation?The horizontal protocol will characterize the spatial variability of the sampled VOCs at intermediate scale and be used to constrain and improve MEGAN (Model of Emissions of Gases and Aerosols from Nature), a framework used for modeling biogenic emissions. The data obtained by the vertical protocol will be used with the mixed-layer inverse-model technique to estimate VOC fluxes. The data and insights gained from this effort will be used to constrain and improve current chemical transport models of atmospheric oxidation and to provide a better understanding of regional and global chemical transport in Amazonia, especially as related to mechanisms of SVOCs and particulate matter production and susceptibility to future Earth-system changes.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目将提高对热带森林生态系统大气化学过程的理解。 移动分析系统将用于表征在不同森林子类型的水平和垂直尺度上挥发性有机化合物（VOC）的排放和沉积。 这些数据将在一系列支持无人机的实验中，该实验在湿和干季的Adolfo Ducke Forest Reserve中，位于亚马逊中部马纳斯北部郊区。 结果将用于改善大气化学建模和数据库，这些模型和数据库表征了植被中生物源化合物的排放。该项目中将解决的科学问题包括以下内容：（1）在森林范围内的VOC发射和沉积的大小和类型是什么是什么是在100's M. m s. m s s eftermediped scapapes上的voc发射和沉积类型。 （2）在湍流行星边界层中反应性VOC的垂直异质性和DIEL周期是什么？ and (3) What is the vertical heterogeneity in the speciation and concentration of semivolatile organic compounds (SVOC) produced as photochemical reaction products of VOC oxidation?The horizo​​ntal protocol will characterize the spatial variability of the sampled VOCs at intermediate scale and be used to constrain and improve MEGAN (Model of Emissions of Gases and Aerosols from Nature), a framework used for modeling biogenic排放。 垂直协议获得的数据将与混合层逆模型技术一起估计VOC通量。从这项工作中获得的数据和见解将用于限制和改善当前大气氧化的化学运输模型，并更好地了解亚马逊地区的区域和全球化学运输，尤其是与SVOC和颗粒物的生产机制以及对地球系统的敏感性相关的，这是NSF的合法任务和依据，这表明了NSF的法定任务和支持，这表明了NSF的范围，并依赖于Internution Internutial revilition，这是构成的依据。 标准。
