Modeling of photochemical air pollution in the Barcelona area with highly disaggregated anthropogenic and biogenic emissions

Simulating Urban-Scale Air Pollutants and Their Predicting Capabilities over the Seoul Metropolitan Area

“…In this study, urban-scale air pollutants such as SO 2 , nitrogen dioxide (NO 2 ), PM 10 , and O 3 have been predicted over the Seoul metropolitan area by employing a prognostic air pollution modeling system called The Air Pollution Model (TAPM) 2 during the period of July 2-11, 2002, using disaggregated emission inventories to evaluate and discuss the predicting capabilities over the Seoul metropolitan area. The operational weather prediction system, Regional Data Assimilation & Prediction System (RDAPS) operated by the Korean Meteorology Administration (KMA) for the regional weather forecasting with the 0.30°g rid resolution was used to provide the larger scale meteorology to the TAPM as initial and boundary conditions.…”

“…However, the precipitations were observed from July 5 to 7, 2002, and relatively higher wind speed of the daily mean prevailed in the 2nd half of the simulation periods over the Seoul metropolitan area. Table 2 presents a summary of the total emissions as well as categorized emissions of SO 2 , NO x , PM 10 , and VOC in the model domain. 7 Total emissions in the domain are 85,119 t/yr, 286,561 t/yr, 83,783 t/yr, and 260,696 t/yr for SO 2, NO x , PM 10 , and VOC, respectively.…”

The total emission of SO 2 mostly originates from point sources (55.4%), NO x and PM 10 from line source (67.8 and 94.8%, respectively), and VOC from area sources (65.5%).…”

“…In the Seoul metropolitan area (ϳ22 million inhabitants), the recent concentration of air pollutants such as particulate matter with aerodynamic diameter Ն10 m (PM 10 ) and ozone (O 3 ) indicates very serious levels caused by the high population and traffic densities, whereas sulfur dioxide (SO 2 ) concentrations have been rapidly decreasing because of the regulations of use of low-sulfur oil since the early 1990s. According to the survey by the Korean National Institute of Environmental Research, the reported numbers of O 3 warning days exceeding the national ambient air quality standard of 120 ppb in 1 hr concentration level were 49, 24, and 43 days from 2000 to 2002.…”

“…The emissions from stationary sources (power plants, oil refineries, steel plant, and residential heating) and various mobile sources (road traffic, harbors and marine traffic, and aviation) are categorized to the area, line, and point sources, and estimated the disaggregated anthropogenic and biogenic emissions (1 km ϫ 1 km) of SO 2 , oxides of nitrogen (NO x ), PM 10 , and volatile organic compounds (VOCs).…”
