英文摘要	Via combining aerosol vertical profiles from the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) and assimilated multi-layer wind profiles from the Modern-Era Retrospective analysis for Research and Applications version 2 (MERRA-2), the horizontal aerosol cross-boundary transport for the Edmonton-Calgary Corridor (ECC) during 2011–2017 was characterized on the basis of aerosol extinction flux. The western and northern boundaries (WB and NB) were revealed as the two aerosol importing gateways for ECC, with the annual mean cross-boundary efficiencies of 0.286 ± 0.231 hr−1 for WB and 0.050 ± 0.025 hr−1 for NB. The annual mean efficiency of the cross eastern boundary (EB) aerosol transport was −0.267 ± 0.243 hr−1, indicating an overall aerosol exporting effect for ECC. More efficient cross southern boundary (SB) aerosol importing processes were found in July (0.049 ± 0.071 hr−1) and August (0.043 ± 0.058 hr−1), which favor the outbreak of Pacific Northwest wildfires. The aerosol emissions from Athabasca oil sands region (AOSR) in Alberta are unlikely to have significant impact on ECC via the cross-NB aerosol transport pathway. The annual mean aerosol extinction flow of 202 ± 2244 km2/h suggested the cross-boundary aerosol importing effect for ECC. The most significant aerosol importing effect for ECC was found in fall, indicated by seasonal mean aerosol extinction flow of 680 ± 1122 km2/h. The observed seasonal variation implied the noticeable influences of aerosol local emissions and cloud-aerosol interactions on ECC aerosol loadings in winter and summer. To obtain a complete picture of aerosol loading budget over ECC, further investigations on the dynamics of aerosol emissions and depositions happened in the ECC atmosphere remain. © 2020 Elsevier Ltd
