Air Pollution and Urban Form: Evidence from Satellite Data

0853467 marshall本研究旨在通过完成遥感获得的NO2浓度与地面测量获得的NO2浓度之间的闭合分析，验证使用高分辨率卫星遥感和化学运输模型来量化城市地区地面NO2浓度。封闭性分析将包括二氧化氮测量在空间和时间尺度上的变化，以及用于表征城市形态/结构/交通网络的参数。重点将主要集中在南加州的南海岸空气盆地（SoCAB），因为它有大量的监测仪和普遍晴朗的气候（低云层覆盖对卫星测量很重要），以及PI马歇尔项目和许多其他研究人员在SoCAB中对空气污染进行了广泛的研究。

0853467 MarshallThis research seeks to validate the use of high resolution satellite sensing and a chemical transport model to quantify ground-level NO2 concentrations in urban areas by completing a closure analysis between the NO2 concentrations obtained by remote sensing and those obtained by ground-level measurements. The variability in spatial and temporal scales of the NO2 measurements and the parameters used to characterize urban form/structure/transportation network will be included in the closure analysis. The focus largely will be on the South Coast Air Basin (SoCAB) in Southern California, owing to its large number of monitors and generally sunny climate (low cloud-cover is important for satellite measurements) and to the extensive body of work on air pollution in the SoCAB by project PI Marshall and many other researchers.
