The Influence of Aged Smoke on Urban Ozone: Aircraft Measurements in Chicago During the 2023 Canadian Wildfires

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract As large wildfires become more frequent and severe in North America due to heightened fuel aridity and fire weather conditions driven by anthropogenic climate change, wildfire smoke has an increasingly important influence on air quality. Transported smoke can impact urban boundary layer ozone (O3) directly, via the entrainment of O3 formed in ...

Long‐term surveillance reveals hybridization by nuclear reassortment and intercontinental spread as major evolutionary drivers in wheat yellow rust

New Phytologist, Volume 251, Issue 4, Page 2091-2106, August 2026.
Documented incursions of Puccinia striiformis 2009–2023 based on sequential resampling of MLGs/pathogen races on different continents. Summary Evolutionary forces affecting crop pathogens, including hybridization and long‐distance dispersal (LDD), may have strong implications for food security and sustainable plant disease control at global scales ...

Characterizing the Source and Formation of Gaseous Nitrated Phenolic Compounds in Urban Shanghai

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Nitrated phenolic compounds (NPs) are important components of brown carbon and contribute to the formation of HONO and OH radicals, yet their gas‐phase abundance and formation mechanisms in polluted urban environments remain poorly understood.

Detection of the most frequent sources of dust storms in Iraq during 2020–2023 using space tools

Kuwait Journal of Science
Dust storms are typical in arid and semi-arid regions such as the Middle East; the frequency and severity of dust storms have grown dramatically in Iraq in recent years. This paper identifies the dust storm sources in Iraq using remotely sensed data from
