Systematic air quality measurements were made in the study region of Toronto during the 2015 Pan-Am games (July 14th – July 29th). These measurements were done using the mobile lab CRUISER (Canadian Regional and Urban Investigation System for Environmental Research) to identify emission sources for characterization and emission inventory development. The measurements included several trace gases (NOx, SO2, CO, VOCs, CO2, CH4, and black carbon), air toxics (H2S, aromatics), atmospheric particles, particle composition and meteorological parameters. Additionally, the measurements were systematically designed to cover 18 sub-regions in and around the Greater Toronto Area multiple times so as to cover the different exposure settings such as traffic, industry, residential, commercial, etc. These data aim to provide a good sample of measurements needed for atmospheric air quality model development.
