NMOC and ozone aloft and their effect on modeled urban ozone production and control strategies
An instrumented aircraft was used to measure non-methane organic carbon (NMOC) and ozone aloft, in the background air masses advected into seven urban areas in the U.S.A. Measurements were made in the layer above the morning surface inversion but below the normal afternoon mixing height. Non-methane hydrocarbon (NMHC) concentrations averaged 21 ppbC while aldehyde concentrations were generally less than 10% of the total NMOC measured. The mean ozone levels found aloft in the areas ranged from 24 ppb to 48 ppb. The data collected were used in an Empirical Kinetic Modeling Approach (EKMA) to model urban ozone production and urban ozone control strategies. It was found that urban ozone production and control strategies were insensitive to NMOC from aloft. Urban ozone production was sensitive to ozone from aloft while ozone control strategies were insensitive to ozone from aloft.
