• Atmospheric Forcing on Solar Energy in Complex Terrain: A Digital Twin Assessment in an Intermontane Basin in Southern Balkans (2026) · Atmosphere · doi

  The complex topography of urbanized mountainous valleys, which restricts natural ventilation and limits the horizontal circulation of air masses. The high spatial variability of pollutants in complex terrain, which poses significant modeling challenges. The need to accurately represent localized fluctuations in aerosol composition and hygroscopic growth of carbonaceous particles.

• First Continuous Aerosol Measurements at Testa Grigia at 3480 m a.s.l.: Aerosol Populations and Dust Transport Dynamics in the Southern European Alps (2026) · Atmospheric Chemistry and Physics · doi

  The paper identifies a gap in the understanding of aerosol populations and transport dynamics at high-elevation observatories. There is a need for integrated monitoring and modeling strategies to predict and mitigate the impact of long-range dust transport on European climate, air quality, and alpine snow.

• Measurement report: Hygroscopicity and mixing state of submicron aerosols in the lower free troposphere over central China: local, regional and long-range transport influences (2026) · Atmospheric chemistry and physics · doi

  There is a lack of measurements of aerosol hygroscopicity in the lower free troposphere. The lower free troposphere is a key atmospheric layer, but measurements are sparse, especially in regions with complex air mass origins. Prior studies have not fully addressed the impact of long-range transport and regional emissions on aerosol composition and hygroscopicity.
