Wildfires are a major source of aerosols during summer in the western United States. Aerosols emitted from wildfires could significantly affect air quality, human health, and global climate. This study conducted comparison aerosol characteristics wildfire smoke-influenced non-smoke-influenced days. Ambient particle size distribution (PSD) data were collected Reno, Nevada, between July 2017 October 2020. During this period, site was impacted by smoke over hundred burning wide range ecosystems States located at different distances measurement site. The days identified using satellite images, hazard mapping system, wind back-trajectory. Positive matrix factorization (PMF) applied to identify main sources their characteristics. observed have number mode diameter 212 nm, which is larger than on (61 nm). In addition increase size, made large contribution PM2.5 CO concentrations. fire-prone months (July, August, September) 2016 2021, 56% 65% 18% 26% concentrations be attributed emissions area.

Abstract During summer 2023 Canada experienced its most intense wildfire season on record. Smoke plumes from these fires advected across the United States (U.S.) Upper Midwest, producing regional scale surface enhancements of PM 2.5 and ozone, as recorded by U.S. monitoring network. These events are notable because they occurred early in fire (May 15‐June 30), produced highest regional‐scale ozone levels ever northern tier during (May–June) or late (July‐August) summer. Specifically, Midwest 50th percentile was greater than any other year since 1995, when network had sufficient coverage to assess levels; 90th 2002. Satellite aircraft measurements demonstrate availability precursors production within smoke plumes.
