Special Issue "Air Pollution Modelling: Local-, Regional-, and Global-Scale Application"
Deadline for manuscript submissions: 30 September 2019
Air pollution problem is inevitably accompanied to our human activities. Severe air pollution situations have been reported especially in emerging countries, and satisfying the air quality standards fully have been still underlying issues. Today, modeling researches is one of the valuable approaches to promote our understanding on the behavior of air pollutants and to be used as regulatory, policy, and environmental decision makings. Such a modeling application range with regard to horizontal grid resolution varied from a few km (local) to hundreds of km (regional) to thousands of km (global).
To foster our current scientific knowledge on modeling potentialities and limitations, we would like to call scientific papers related to air pollution modeling applied for urban-, regional-, and global-scale on this special issue in the journal of Atmosphere. By collecting devoted papers, this theme seeks the future strategies for modeling researches across multi-scales. Modeling is not limited on the Eulerian and Lagrangian models, and other modeling techniques (e.g., box model, receptor model) are welcome. The online-coupled chemical transport model integrated with meteorological model will also contribute to this special issue. This topic would represent a notable contribution to this important scientific field.

Abstract: Due to high anthropogenic emissions and the basin landform, Sichuan Basin (SCB) with 18 cities in southwestern China is one of the regions that suffer from severe air pollution in the country. In order to preliminarily understand how much emissions need to be reduced to achieve the World Health Organization (WHO) guidelines and China’s National Ambient Air Quality standards (CNAAQs) for ozone (O3) and particulate matter with an aerodynamic diameter less than 2.5 μm (PM2.5), air pollutant concentrations under 10% to 90% anthropogenic emission reductions were simulated by using the Community Multi-scale Air Quality (CMAQ) and the Weather Research and Forecasting (WRF) models for the winter and summer, 2015. As PM2.5 concentrations are highest in winter and the photochemical production of O3 is greatest in summer, we simulated air pollution for the two seasons. The attainment of O3 and PM2.5 based on the WHO guideline and CNAAQs under different emission reductions were calculated and its present great spatial variations. The most polluted areas are the Chengdu and Chongqing. For the two cities, in order to make daily PM2.5 less than the WHO guideline in the winter, anthropogenic emissions within the SCB should be reduced by 90% most of time. In the summer, a reduction in anthropogenic emissions may increase O3 concentrations occasionally in Chengdu and Chongqing. This study suggests that there is a need to greatly reduce anthpogenic emissions in order to efficiently protect human health in the SCB.

Abstract: Located in the transitional region from Sichuan Basin to Qinghai-Tibetan Plateau, the eastern rim of the Qinghai-TibetanPlateau(ERQTP)is a large, complex ecological zone and abiodiversity hotspot.Anthropogenic air pollutants transported from Sichuan Basin and other regions are likely to accumulate and deposit along the ERQTP, leading to ozone pollution. Stratospheric ozone in Qinghai-TibetanPlateau is also likely to invadetroposphere. We hypothesis that vegetation in thisareaexposes toa high ozone dose.We use Source-oriented Community Multi-scale AirQuality (source-oriented CMAQ) to calculate ozone exposure indices of M7, M24, N100, AOT40f, SUM60, and W126, with a spatial resolution of 4 km along the ERQTP. Based on these indices, we identify high ozone concentration episodes and assess potentialnegative impacts of ozoneon local vegetation.Sources of air masses arealsoanalyzed in combination with CO, meteorology and HYSPLIT, exploring whether the air mass causing increasedozone concentration alongthe ERQTPis from Sichuan Basin or from the stratosphere.Furthermore, source-oriented CMAQ is used to simulate source of ozone along the ERQTP, to quantify industrial source and regional transmission of ozone and its precursors, and to determine contribution of natural and anthropogenic sources to local ozone concentrations. Study of ozone exposure on vegetation along the ERQTP canhelp to take measures to protect local vegetation
