• Urban ozone formation and sensitivities to volatile chemical products, cooking emissions, and NO _<i>x</i> upwind of and within two Los Angeles Basin cities

  Atmospheric chemistry and physics · 2025-01-28 · 15 citations

  articleOpen access

  Abstract. Volatile chemical products (VCPs) and other non-traditional anthropogenic sources, such as cooking, contribute substantially to the volatile organic compound (VOC) budget in urban areas, but their impact on ozone formation is less certain. This study employs Lagrangian box modeling and sensitivity analyses to evaluate ozone response to sector-specific VOC and nitrogen oxide (NOx) emissions in two Los Angeles (LA) Basin cities during the summer of 2021. The model simulated the photochem…

• Online Calibration of a Chemical Ionization Mass Spectrometer for Multifunctional Biogenic Organic Nitrates

  ACS ES&T Air · 2024-08-08 · 6 citations

  article

  Multifunctional organic nitrates derived from biogenic volatile organic compounds are important for understanding ozone and secondary organic aerosol production from oxidation reactions in the presence of nitrogen oxides. Their measurement is challenging, in part because the quantification of these compounds is difficult and time consuming due to the techniques required to synthesize and purify authentic standards. We describe a novel online synthesis and separation technique and demonstrate its…

• Aqueous‐Phase Processing Affects the Formation and Size Distribution of Aerosol Organic Functional Groups During Heavy Pollution

  Journal of Geophysical Research Atmospheres · 2025-02-04 · 5 citations

  articleOpen accessSenior authorCorresponding

  Abstract Size‐resolved organic functional group (OFG) concentrations in aerosol particles were measured during January−February 2019 in Hefei, a major urban city in eastern China. Alkane, carboxylic acid, and hydroxyl groups were the main components of the organic aerosol (OA), contributing 35.0%, 22.5%, and 21.8%, respectively. The mass concentrations and size distributions of the OFGs strongly depended on ambient relative humidity (RH). Specifically, the OFG mass concentrations were 50% higher…

• Urban ozone formation and sensitivities to volatile chemical products, cooking emissions, and NO _x across the Los Angeles Basin

  2024-07-15 · 2 citations

  preprintOpen accessCorresponding

  Abstract. Volatile chemical products (VCPs) and other non-traditional anthropogenic sources, such as cooking, contribute substantially to the volatile organic compound (VOC) budget in urban areas. The impact of these emissions on ozone formation and urban atmospheric chemistry is uncertain. This study employs detailed Lagrangian box modeling and sensitivity analyses to evaluate ozone response to sector-specific VOC and nitrogen oxide (NOx) emissions in the Los Angeles (LA) Basin during the summe…
