AB: A systematic and comprehensive method of air pollutant trends analysis is critical in benchmarking change in air quality conditions and informing policy makers (EPA, 2007; Environment Canada, 2006; NARSTO, 2004). AOD derived from the MODIS instrument aboard the NASA Terra and Aqua satellites is correlated with the ground- based AErosol RObotic NETwork (AERONET, AEROCAN in Canada) AOD and compared to trends in ambient fine particulate matter (PM_2.5) in the United States-Canada border region from May-September, 2000-2006. Trends are calculated using the change in AOD or PM_2.5 over the given time period, determined from simple linear regression at each point in a standard grid. The method enables robust comparison of AERONET AOD and regridded MODIS AOD, as well as comparison of trends in MODIS AOD and ambient PM_2.5, between ground site, month of study, and satellite. Results were tabulated for comparison at each of these levels (i.e. For the month of July, Aqua MODIS AOD correlated well with PM_2.5 at one site, R² = 0.78). The research results convey the utility of MODIS AOD to assess air quality trends in international regions with spatially sparse or variable ground PM_2.5 monitors, and to address the impacts of policy implementation and inform decision-making.
