The Air Indicator Report for Public Awareness and Community Tracking v.3 (AIRPACT-3) air quality forecast model simulates EPA criteria pollutants and their precursors, providing quantitative descriptions of regional air quality in the Pacific Northwest. This study focuses on comparing AIRPACT-3 simulations to satellite-based retrievals of atmospheric pollutants made by select instruments flying in NASA’s Earth Observing System. Products from the Ozone Monitoring Instrument (OMI), Atmospheric Infra-Red Sounder (AIRS), Measurement of Pollution in the Troposphere (MOPITT), Moderate Resolution Imaging Spectroradiometer (MODIS), and the Cloud-Aerosol LiDAR and Infrared Pathfinder Satellite Observations (CALIPSO) are used in an effort to validate AIRPACT-3 and serve as a basis to implement near real-time satellite resources for AIRPACT-3 users in the future. Focus is given to satellite-derived nitrogen dioxide, aerosol subtypes, aerosol optical depth, and carbon monoxide. The horizontal and vertical distributions of NO2, CO and aerosol pollutants in AIRPACT-3 are shown to be quite reasonable, but signs of overestimation of wildfire emissions are observed. New dynamic chemical boundary conditions in AIRPACT-3 derived from the National Center for Atmospheric Research (NCAR) forecast results are shown to eliminate carbon monoxide column bias in the model. Monthly and seasonal trends of OMI NO2 are found to correspond to urban employment and other factors during the economic downturn. Wildfire-generated aerosols are shown to be too persistent in AIRPACT-3 but fire locations are found to be reasonable. The broader impacts of using the context of engineering sciences within middle school mathematics lessons are also discussed.
