Limitation of O3 Dry Deposition by Elevated-Source NO Emissions and Surface Dryness in Urban Environments

Abstract 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...

Rapid Declinesin European Traffic NO x and NMVOC EmissionsRevealed by Eddy-Covarianceand Remote Sensing

Abstract 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...

Evaluation of the Impact of Aged Biomass Burning Emissions on the Global Ozone From the Surface to the Lower Stratosphere

Abstract Biomass burning (BB) is a major global sources of ozone (O 3 ) precursors, including nitrogen oxides (NO x ), carbon monoxide (CO), and volatile organic compounds (VOCs). Here, we combine Community Earth System Model 1 with airborne measurements from the NASA Atmospheric...
