“…Notwithstanding that there is clearly variability in wind trajectories, yet, they are typical trajectories where air masses come from the airport. Henry-L'Heureux et al ( 2021 ) demonstrated that at the airport of Montreal the dominant wind direction is from the southwest and that the impacts of the emissions of CO, NO x , and PM coming from the airport are heavily affected by wind especially the dominant winds.…”

“…It is possible that the particles found in the samples come from the engine exhaust of planes, as previously suggested (Rahim et al 2019 ), as part of the airport of Montreal is located northwest of the sampling location and a residential area with low local traffic is located to the west (Rahim et al 2019 ) and plane trajectories from/to the airport include the sampling area. Moreover, strong winds are more frequent in winter (Henry-L'Heureux et al 2021 ). Thereby in winter, it results in a faster dispersion of pollutants, resulting in higher pollutant concentrations at the surface in winter than in summer (Henry-L'Heureux et al 2021 ).…”

Airports are identified hotspots for air pollution, notably for fine particles (PM 2.5 ) that are pivotal in aerosol-cloud interaction processes of climate change and human health. We herein studied the field observation and statistical analysis of 10-year data of PM 2.5 and selected emitted co-pollutants (CO, NO x , and O 3 ), in the vicinity of three major Canadian airports, with moderate to cold climates. The decadal data analysis indicated that in colder climate airports, pollutants like PM 2.5 and CO accumulate disproportionally to their emissions in fall and winter, in comparison to airports in milder climates. Decadal daily averages and standard errors of PM 2.5 concentrations were as follows: Vancouver, 5.31 ± 0.017; Toronto, 6.71 ± 0.199; and Montreal, 7.52 ± 0.023 μg/m 3 . The smallest and the coldest airport with the least flights/passengers had the highest PM 2.5 concentration. QQQ-ICP-MS/MS and HR-S/TEM analysis of aerosols near Montreal Airport indicated a wide range of emerging contaminants (Cd, Mo, Co, As, Ni, Cr, and Pb) ranging from 0.90 to 622 μg/L, which were also observed in the atmosphere. During the lockdown, a pronounced decrease in the concentrations of PM 2.5 and submicron particles, including nanoparticles , in residential areas close to airports was observed, conforming with the recommended workplace health thresholds (~ 2 × 10 4 cm −3 ), while before the lockdown, condensable particles were up to ~ 1 × 10 5 cm −3 . Targeted reduction of PM 2.5 emission is recommended for cold climate regions.

“…To compensate for the shortcomings inherent in flow representation, they usually integrate complex dispersion processes (Tominaga & Stathopoulos, 2013 ); e.g., atmospheric stratification, buoyancy, chemistry, deposition, and concentration fluctuations. Gaussian models were used in airport environments (Celikel et al, 2004 ; Henry-Lheureux et al, 2021 ; Mazaheri et al, 2011 ; Winther et al, 2015 ; Yang et al, 2018 ; Yim et al, 2013 ) to develop a comprehensive formal assessment of emission inventories (aircraft main engines, APUs, ground-support equipment (GSE), ground-access vehicles (GAVs), private vehicle, stationary sources, etc. ), because they are designed to enable different sources of pollutants (Winther et al, 2015 ) (main engines, APUs, GSE, etc.).…”

“…), because they are designed to enable different sources of pollutants (Winther et al, 2015 ) (main engines, APUs, GSE, etc.). For example, a Gaussian model was used to study NO x and CO emissions from Montreal’s international airport (YUL) (Henry-Lheureux et al, 2021 ). The study investigated the impact of both air traffic and GAVs on the whole island of Montreal (56 × 40 km) discretized with a spatial resolution of 110 m. Results under different atmospheric conditions show that pollutants were dispersed further and their concentrations higher during the winter season than in the summer season.…”

Pollutant emissions from aircraft operations contribute to the degradation of air quality in and around airports. Meeting the ICAO’s environmental certification standards regarding both gaseous and particulate aircraft engine emissions is one of the main challenges for air-transportation development over the coming years. To increase the accuracy of airport air pollution monitoring and prediction, advanced decision-making tools need to be developed. In this context, the present study aimed at demonstrating the modeling capabilities of an innovative methodology that accounts for the microscale evolution of aircraft emissions, both spatially and temporally. For this purpose, 3D high-resolution CFD simulations were carried out in the CAEPport configuration (medium-size mock airport) as defined by the Committee on Aviation Environmental Protection (CAEP/8) for local air-quality assessment. The modeled domain extends up to 8 km around the airport. A spatial resolution down to 1 m was used around buildings to refine the prediction of pollutant-emission concentrations. The model accounts for ambient meteorological conditions along with the background chemical composition. NO x emissions from main engines and auxiliary power units (APUs) were individually tracked along LTO trajectories with a time resolution down to 1 s. The impact of atmospheric stability was investigated in three cases, i.e., stable, neutral, and unstable. The results show NO 2 dominating in apron areas due to the low power setting of main engines along APU contribution during extended parking. Conversely, a domination of NO emissions was observed at the runway threshold due to the high power setting of the main engines. Stable atmospheric conditions promoted higher NO and NO 2 concentrations as compared to both neutral and unstable cases. The use of APUs contributed to higher concentrations of both NO and NO 2 emissions and especially of NO 2 in terminal areas.
