Description:

Modeled source attribution information from the Community Multiscale Air Quality model was coupled with ambient data from the 2011 Deriving Information on Surface conditions from Column and Vertically Resolved Observations Relevant to Air Quality Baltimore ﬁeld study. We assess source contributions and evaluate the utility of using aircraft measured CO and NO yrelationships to constrain emission inventories. We derive ambient and modeled ΔCO:ΔNO yratios that have previously been interpreted to represent CO:NO yratios in emissions from local sources. Modeled and measured ΔCO:ΔNO yare similar; however, measured ΔCO:ΔNO yhas much more daily variability than modeled
