Long-term trend analyses of airborne particulate matter (PM) typically assume that a single trend direction persists across the entire monitoring period, potentially masking underlying structural changes caused by shifts in...
Secondary organic aerosols (SOA) is a major component of fine particles affecting air quality and climate, yet its formation from biogenic volatile organic compounds via nighttime NO 3 oxidation remains poorly understood.
Street-view imagery was used to assess street greenery and examine how greenery quantity and configuration relate to PM concentrations. Low-level barriers formed by greenery may restrict ventilation, potentially explaining these associations.
The Minamata Convention on Mercury has highlighted the need for improved atmospheric mercury monitoring, yet observations of gaseous elemental mercury (GEM) remain scarce across the Southern Hemisphere. No atmospheric GEM...
The role of entrainment from above the canopy, deposition to soil and vegetation, chemical reactions and soil emissions of NO in defining the nocturnal vertical gradients of NO, NO 2 , and O 3 in forested regions is investigated.
