• W4293733549 abstract "<strong class=journal-contentHeaderColor>Abstract.</strong> Nitrate (NO<span class=inline-formula>₃^−)</span> has been the dominant and the least reduced chemical component of fine particulate matter (PM<span class=inline-formula>_2.5)</span> since the stringent emission controls implemented in China in 2013. The formation pathways of NO<span class=inline-formula>₃^−</span> vary seasonally and differ substantially in daytime vs. nighttime. They are affected by precursor emissions, atmospheric oxidation capacity, and meteorological conditions. Understanding NO<span class=inline-formula>₃^−</span> formation pathways provides insights for the design of effective emission control strategies to mitigate NO<span class=inline-formula>₃^−</span> pollution. In this study, the Community Multiscale Air Quality (CMAQ) model was applied to investigate the impact of regional transport, predominant physical processes, and different formation pathways to NO<span class=inline-formula>₃^−</span> and total nitrate (TNO<span class=inline-formula>₃</span>, i.e., HNO<span class=inline-formula>₃+</span> NO<span class=inline-formula>₃^−</span>) production in the Yangtze River Delta (YRD) region during the four seasons of 2017.

Local emissions and regional transportation contribute to NO<span class=inline-formula>₃^−</span> concentrations throughout the YRD region by 50 %–62 % and 38 %–50 %, respectively. The majority of the regional transport of NO<span class=inline-formula>₃^−</span> concentrations is contributed by indirect transport (i.e., NO<span class=inline-formula>₃^−</span> formed by transported precursors reacting with local precursors). Aerosol (AERO, including condensation, coagulation, new particle formation, and aerosol growth) processes are the dominant source of NO<span class=inline-formula>₃^−</span> formation. In summer, NO<span class=inline-formula>₃^−</span> formation is dominated by AERO and total transport (TRAN, sum of horizontal and vertical transport) processes. The OH <span class=inline-formula>+</span> NO<span class=inline-formula>₂</span> pathway contributes to 60 %–83 % of the TNO<span class=inline-formula>₃</span> production, and the N<span class=inline-formula>₂</span>O<span class=inline-formula>₅</span> heterogeneous (HET N<span class=inline-formula>₂</span>O<span class=inline-formula>₅)</span> pathway contributes to 10 %–36 % in the YRD region. HET N<span class=inline-formula>₂</span>O<span class=inline-formula>₅</span> contribution becomes more important in cold seasons than warm seasons. Within the planetary boundary layer in Shanghai, the TNO<span class=inline-formula>₃</span> production is dominated by the OH <span class=inline-formula>+</span> NO<span class=inline-formula>₂</span> pathway during the day (98 %) in the summer and spring and by the HET N<span class=inline-formula>₂</span>O<span class=inline-formula>₅</span> pathway during the night (61 %) in the winter. Local contributions dominate the OH <span class=inline-formula>+</span> NO<span class=inline-formula>₂</span> pathway for TNO<span class=inline-formula>₃</span> production during the day, while indirect transport dominates the HET N<span class=inline-formula>₂</span>O<span class=inline-formula>₅</span> pathway at night." @default.
