Tropospheric ozone (O3) is a major air pollutant that adversely affects human health, climate and ecosystems. However, its removal in urban environments remains poorly represented in air-quality and climate models, largely due to limited flux-based observations of urban O3 deposition. Using eddy-covariance flux measure...

Reliable quantification of anthropogenic emission trends remains a major uncertainty in air-quality and climate assessments. Here we present nearly a decade of eddy-covariance flux measurements of NOx, nonmethane volatile organic compounds (NMVOCs), and CO2 in the Alpine city of Innsbruck, providing direct top-down c...

Mitigating ozone pollution remains a pressing challenge for megacities worldwide. Biogenic volatile organic compounds (VOCs) are proposed as pivotal precursors to urban ozone formation. However, direct observational evidence is scarce and the extent of this effect across cities is unclear. Here, by combining an unprece...
