项目摘要
This project includes a combination of field work, laboratory analysis, and modeling to improve the understanding of the complex interactions between human and natural systems at the interface of urban cities and coastal oceans. This research focuses on quantifying and characterizing factors controlling the marine emissions of trace gases in an urban coastal southern California location known to be impacted by run-off and anthropogenic emissions. The data collected in this study will be used to estimate the current and future influences of these trace gas fluxes on global climate and local air quality.This work has three primary aims: (1) Characterize the environmental drivers and anthropogenic influences controlling coastal secondary marine aerosol (SMA) precursors through controlled mesocosm experiments and in-situ measurement campaigns; (2) Integrate the gas-phase emissions characterized above into updated online coastal emissions inventories; and (3) Model impacts of the modified ocean emissions under current and future climate scenarios. The potential impacts of chemical speciation, timing, and temperature dependence identified through the field campaign and laboratory measurements will be explored using both global and regional atmospheric simulations. This effort will provide new datasets for a largely under-constrained anthropogenic-biogenic system, and lead to a subsequent improvement of emission inventories and regional and global modeling to increase the understanding of the formation of coastal secondary marine aerosols (SMA) in the atmosphere.This project includes support for a postdoctoral scholar, several graduate students, and opportunities for the involvement of citizen science.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.
该项目包括实地工作、实验室分析和建模相结合,以提高对城市和沿海海洋界面人类与自然系统之间复杂相互作用的理解。本研究的重点是量化和表征控制南加州沿海城市痕量气体海洋排放的因素,该地区已知受到径流和人为排放的影响。本研究收集的数据将用于估计这些微量气体通量对全球气候和局部空气质量的当前和未来影响。本研究有三个主要目的:(1)通过控制的中尺度实验和原位测量活动,表征控制沿海次生海洋气溶胶(SMA)前体的环境驱动因素和人为影响;(2)将上述特征的气相排放纳入更新的沿海在线排放清单;(3)当前和未来气候情景下海洋排放变化的模式影响。通过野外活动和实验室测量确定的化学形态、时间和温度依赖性的潜在影响将利用全球和区域大气模拟进行探索。这项工作将为很大程度上不受约束的人为-生物系统提供新的数据集,并导致排放清单和区域和全球模型的后续改进,以增加对大气中沿海次生海洋气溶胶(SMA)形成的理解。该项目包括对一名博士后学者、几名研究生的支持,以及公民科学参与的机会。该奖项反映了美国国家科学基金会的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
