The Air Indicator Report for Public Awareness and Community Tracking (AIRPACT) air quality 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 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 and serve as a basis to implement near-real time satellite resources for AIRPACT users in the future. Focus is given to satellite-derived nitrogen dioxide, aerosol subtypes, aerosol optical depth, and carbon monoxide. The horizontal and vertical distribution of pollutants in the AIRPACT is shown to be quite reasonable, but signs of overestimation of wildfire emissions are observed. The broader impacts of using engineering sciences on culturally relevant education is also discussed.
