Biogenic volatile organic compound (BVOC) emissions have long been known to play vital roles in modulating the formation of ozone and secondary aerosols (SOAs). While early studies evaluated their impact globally or regionally, BVOC emitted from urban green spaces (denoted as U-BVOC emissions) largely ignored primarily due failure low-resolution land cover resolving such processes, but also because important contribution BVOCs was previously unrecognized. In this study, by utilizing a recently released high-resolution dataset, we develop first set emission inventories U-BVOCs China at spatial resolutions high 1 km. This new dataset resolved densely distributed core areas. The megacities could account for large fraction total emissions, good agreement interannual variations between concentrations over certain regions stresses potentially crucial role influencing variations. newly constructed inventory is expected provide an improved enable research community re-examine modulation on ozone, SOA, atmospheric chemistry environments.

In this study, tropospheric formaldehyde (HCHO) vertical column densities (VCDs) were measured using multi-axis differential optical absorption spectroscopy (MAX-DOAS) from January to November 2019 in Shenyang, Northeast China. The maximum HCHO VCD value appeared the summer (1.74 × 1016 molec/cm2), due increased photo-oxidation of volatile organic compounds (VOCs). concentrations 08:00 and peaked near 13:00, which was mainly attributed release isoprene plants enhanced photolysis at noon. VCDs observed by MAX-DOAS OMI have a good correlation coefficient (R) 0.78, contributions primary secondary sources distinguished multi-linear regression model. anthropogenic emissions showed unobvious seasonal variations, relatively stable Shenyang. Secondary contributed 82.62%, 83.90%, 78.90%, 41.53% total ambient during winter, spring, summer, autumn, respectively. We also found (R = 0.78) between vegetation index (EVI) VCDs, indicating that oxidation biogenic (BVOCs) main source HCHO. ratio nitrogen dioxide (NO2) used as tracer analyze O3-NOx-VOC sensitivities. VOC-limited, VOC-NOx-limited, NOx-limited regimes made up 93.67%, 6.23%, 0.11% overall measurements, addition, summertime ozone (O3) sensitivity changed VOC-limited morning VOC-NOx-limited afternoon. Therefore, study offers information on corresponding O3 production sensitivities support strategic management decisions.
