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.

0853467马歇尔本研究旨在验证使用高分辨率卫星传感和化学传输模型，以量化地面NO2浓度在城市地区完成一个封闭的分析之间的NO2浓度通过遥感和地面测量获得。封闭分析将包括NO2测量的空间和时间尺度的变化以及用于表征城市形态/结构/交通网络的参数。 重点将主要放在南加州的南海岸空气盆地（SoCAB），这是由于其大量的监测器和通常阳光充足的气候（低云量对卫星测量很重要），以及PI项目马歇尔和许多其他研究人员在SoCAB的空气污染方面的大量工作。
