A review of the current state of emission inventories of volatile organic compounds (VOC) and NOx data compiled for urban areas in the U.S. is presented. The study reveals great differences in the gross emission magnitudes when compared with corresponding ambient air concentration data. The VOC emissions data are, in general, shown to be underestimated by factors exceeding 3 or more for most cities. The aggregated emission from urban areas is determined from measurements of excess crosswind and vertically integrated pollutant concentration over background in the urban plume just downwind of the emissions area.
