Data from the Ozone Monitoring Instrument (OMI) and Tropospheric Emission Spectrometer (TES) instruments on NASA's Aura satellite are being applied for air quality analysis and modeling purposes. We summarize the types of applications that are being attempted, discuss the successes that have been achieved, and outline the limitations of the data. Column amounts of the trace gases O3, NO2, SO2, HCHO and aerosol optical depths from OMI are being used for estimating emissions, for assimilation into air quality forecast models, and in analyzing the impacts of major source regions. Profiles of CO and O3 from TES are being used in analyses of long range transport of air pollutants and the air quality impacts of megacities and boreal fires. Assimilation of OMI ozone data into an air quality prediction system has proven successful. Limitations of the Aura data include inadequate temporal sampling, relative insensitivity to boundary layer pollution, limited vertical profile information, and cloud interference. All of these limitations must be carefully considered when applying the Aura data for air quality purposes. Possible future expansion of Aura data applications will be discussed.
