Observed and Modeled Changes in Boundary‐Layer and Surface‐Level Actinic Flux Due To Wildfire Smoke Plumes in the California Central Valley in Summer 2018

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract Wildfire smoke is increasingly degrading U.S. air quality via the emission and transport of pollutants. Smoke's direct role as a pollutant is well‐documented; however, smoke also affects pollutant concentration indirectly by changing the shortwave actinic flux necessary for photochemical reactions.

Geostationary Air Quality Monitoring Substantiates Column NO2 as a Better O3 Formation Regime Indicator in China

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract China has become a global hotspot of ozone (O3) pollution, and understanding O3 formation regime is crucial for air quality management. Satellite‐observed formaldehyde‐to‐nitrogen‐dioxide ratio (HCHO/NO2, FNR) has long been demonstrated as an efficient way to infer O3 formation regime.

Exploring the Relationship Between Particle and Gas Phase Chlorine in Continental Winter

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract Road salt is widely used in many North American and European urban wintertime environments, yet its impacts on tropospheric reactive chlorine species are still uncertain. We present ambient size‐resolved particle‐phase chloride (Cl−) and hydrogen chloride (HCl) measurements that were made in continental urban winter (Toronto, ON) concurrent ...

Aging Lifetime of Atmospheric Brown Carbon Determined From Measurements of Wildfire Carbonaceous Aerosol in Western Canada

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract The atmospheric abundance of black carbon (BC) and brown carbon (BrC) aerosol particles has been measured using aethalometry at four locations (Kamloops, BC; Prince George, BC; Joussard, AB; East Trout Lake, SK) in Western Canada through the 2023 and 2024 wildfire seasons (June to November).

Crystals as Rockets: Modulation of the Salient Temperature in Cocrystals by Solvent Mixture Composition

open access: yesAngewandte Chemie, Volume 138, Issue 18, 27 April 2026.
Compositionally engineered mixed solvated cocrystals enable modulation of thermosalient actuation. Guest ratio controls thermosalient temperature and propulsion intensity, providing a tunable platform for designing crystalline systems that exhibit stimuli‐responsive mechanical motion.
