Characterization of Atmospheric Organic Aerosol through Integrated Analysis and Modeling of MILAGRO-2006 Multi-platform Measurements

通过 MILAGRO-2006 多平台测量的集成分析和建模表征大气有机气溶胶

基本信息

项目摘要

This award will support studies of organic and other aerosols and their regional impact through the integration of modeling studies with the extensive multi-platform ground-, aircraft- and satellite-based measurements obtained during the 2006 MILAGRO (Megacity Initiative: Local And Global Research Observations) Campaign in the Mexico City Metropolitan Area. An updated comprehensive measurement-based emissions inventory of gases and particulate matter (PM) will be developed and will be used as input to chemical transport models. In turn, the capability of the chemical transport models to reproduce the rich MILAGRO PM and trace gas data sets will be evaluated. Chemical transport modeling studies will be conducted using a modified version of an on-line coupled Weather Research Forecasting Model with Chemistry (WRF-CHEM). A meteorological ensemble technique will be used to investigate the meteorological impacts on PM simulations. The project will address five specific objectives: i) to improve the estimates of gaseous and PM emissions and the meteorological fields; ii) to characterize formation of secondary organic aerosol (SOA) from different emission sources; iii) to assess the impact of biomass burning and biogenic sources on PM; iv) to quantify the relative contribution of anthropogenic vs. natural sources of PM on the regional scale; and v) to investigate the impact of urban aerosols on regional photochemistry and meteorology.The project will provide support for postdoctoral researchers. The results of this study will be of value to the scientific community, but also be used in presentations to Mexican authorities interested in regional air quality.
该奖项将支持对有机和其他气溶胶及其区域影响的研究,方法是将模拟研究与2006年在墨西哥城大都市区开展的Milagro(大城市倡议:当地和全球研究观测)运动期间获得的广泛的多平台地面、飞机和卫星测量相结合。将编制最新的基于测量的气体和颗粒物(PM)排放清单,并将用作化学品运输模型的输入。反过来,将评估化学传输模型再现丰富的Milagro PM和痕量气体数据集的能力。将使用在线天气研究预报模型与化学耦合(WRF-CHEM)的修订版进行化学输送模拟研究。将使用气象集合技术来研究气象对PM模拟的影响。该项目将针对五个具体目标:i)改进对气体和PM排放以及气象场的估计;ii)表征来自不同排放源的二次有机气溶胶(SOA)的形成;iii)评估生物质燃烧和生物来源对PM的影响;iv)量化区域尺度上PM的人为来源和自然来源的相对贡献;以及v)调查城市气溶胶对区域光化学和气象学的影响。这项研究的结果将对科学界有价值,但也将用于向墨西哥当局介绍对区域空气质量感兴趣的情况。
