Abstract. A typical multi-day ozone (O3) pollution event was chosen to explore the atmospheric oxidation capacity (AOC), OH reactivity, radical chemistry, and O3 mechanism in a coastal city of southeastern China, with an observation-based model coupled Master Chemical Mechanism (OBM-MCM). The hydroxyl (OH) predominant oxidant (90 ± 25 %) for daytime AOC, while NO3 played important role AOC during nighttime (72 9 %). Oxygenated volatile organic compounds (OVOCs; 30 8 %), NO2 (29 CO (25 5 were...
Abstract. Nitrous acid (HONO), a vital precursor of atmospheric hydroxyl radicals (OH), has been extensively investigated to understand its characteristics and formation mechanisms. However, discerning fundamental mechanisms across diverse environments remains challenging. This study utilizes measurements from Mount Lao, coastal mountain in eastern China, an observation-based chemical box model (OBM) examine HONO budgets their subsequent impacts on oxidizing capacity. The incorporates...
Rain and snow water samples were collected from Sep. 2010 to Jun. 2011 at a semi-rural site in Ya’an, city located the rain-belt along Tibetan Plateau, characterize chemical composition sources of precipitation. The severely acidified with an annual volume-weighted mean (VWM) pH 4.03 acid rain frequency 79%. SO42- NH4+ most abundant ions, followed by Ca2+, H+, NO3-, Cl-, K+, Na+, F- Mg2+. acidity was predominantly generated H2SO4 HNO3, which neutralized Ca2+ as much 65%. NH3 played major...
In recent years, the magnitude and frequency of regional ozone (O
Heterogeneous reactions of NO2 on surfaces seem to be an important sink for and a source HONO in the atmosphere. Although heterogeneous have been extensively investigated laboratory studies, kinetic data about this reaction real ambient are limited. Therefore, present study, we urban grime, representative surface film areas, under various experimental conditions using Teflon box system. The role that light played these was also explored. It found uptake coefficient (γ) yield both were...
The petroleum industry is a significant source of anthropogenic volatile organic compounds (VOCs), but up to now, its exact impact on urban VOCs and ozone (O3) remains unclear. This study conducted year-long VOC observations in Dongying, China, industrial region. from the (oil gas volatilization petrochemical production) were identified by employing positive matrix factorization model, their contribution O3 formation was quantitatively evaluated using an observation-based chemical box model....
Abstract. To develop effective strategies for controlling both PM2.5 and O3 levels, it is crucial to understand their synergistic mechanisms key precursors the atmospheric physiochemical processes involved. In this study, a wintertime co-occurring pollution event in coastal city southeast China was investigated based on high-time-resolution measurements of criteria air pollutants chemical compositions PM2.5, precursors, such as NOx, HCHO, volatile organic compounds (VOCs). The results study...
Installed solar photovoltaic generation is expanding fast in western China, with total capacity accounting for >15% of global capacity. However, severe aerosol pollution over China has weakened the radiation reaching panels. We assessed impact on power at city level from 2014 to 2018. Over northwestern regions, aerosols reduced annual average by 0.15–0.31 kWh/m 2 /day relative clean air conditions, a decrease 4.8–9.0%. The had significant seasonal variations. Aerosols can exert an...
Carbonyl compounds play a crucial role in the formation of ozone (O
We analyzed two data sets of atmospheric formaldehyde (FA) at an urban site in the Shanghai megacity during summer 2017 and winter 2017/18, with primary objective determining emission ratio versus carbon monoxide (CO). Through photochemical age method minimum R squared (MRS) method, we derived release ratios 3.37 ppbv (ppmv CO)-1 4.04 CO)-1, respectively. The error both estimations is within ±20%, indicating consistency results. recognized hourly determined from MRS to be indicative actual...
The mechanism of the reaction imidogen (NH) with fulminic acid (HCNO) has been investigated theoretically using multiconfigurational self-consistent-field theory (MCSCF), multireference Rayleigh-Schrodinger perturbation (RSPT2), and coupled cluster (CC) along complete basis set extrapolations (CBS). calculations show that NH + HCNO takes place via an N → C addition predominantly by surmounting a small barrier (ca. ∼3 kcal/mol). adduct is HC(NH)NO in triplet state exothermicity more than 60...
Abstract In recent years, as a renewable resource, solar energy has been widely used and bright prospects. Studies have shown that air pollution certain impact on photovoltaic power generation, but the quantitively influence of factors is not clear. Though analysis experimental records various pollutants meteorological factors, calculation results extinction coefficient generation efficiency, main affecting are determined quantitively.
