AB: Nitrogen oxide emissions from mobile sources can strongly influence photochemical oxidant and secondary particulate nitrate formation in the troposphere. Quantification of the impact of mobile NOx sources requires accurate characterization of mobile source emissions under real world operating conditions. We have developed a mobile laboratory equipped with fast response trace gas sensors that has been deployed to quantifyon-road NOx fleet average emissions, NOx emissions from individual on-road vehicles, and aircraft NOx emissions at airports during taxi, take-off, and tarmac operations. Measurement strategies and instrumentation will be described and results of NOx emissions from a range of on-road vehicles, urban traffic mixes, and commercial aircraft will be presented.
