“…Such large grid cells artificially dilute the imported pollution plumes as well as local emissions of ozone precursors in the receptor region, and also smooth the topography of the receptor region, removing the influence of terrain-driven transport mechanisms that affect the mixing of imported pollution down to the surface. However, recent model studies have used finer-scale grids to avoid the problems associated with coarse-resolution models (Lin et al, 2012b;Huang et al, 2013;Zhang et al, 2014;Choi et al, 2014). Because these finer-resolution models provide more realistic simulations of observed pollution plumes scientists have greater confidence in their quantification of the contribution of imported pollution at the surface of a receptor region.…”

“…More than 80 % of summertime upper tropospheric NO x above the eastern United States is produced by lightning (Cooper et al, 2009) and can be a significant contributor to surface ozone (Hudman et al, 2009). Lightning NO x (NO 2 ) has been detected from space (Beirle et al, 2010;Choi et al, 2005). The lightning-produced NO perturbs atmospheric composition in several ways relevant to climate, as NO is an important determinant of OH / HO 2 ratios via Reaction (R3).…”

Abstract. Ozone holds a certain fascination in atmospheric science. It is ubiquitous in the atmosphere, central to tropospheric oxidation chemistry, yet harmful to human and ecosystem health as well as being an important greenhouse gas. It is not emitted into the atmosphere but is a by-product of the very oxidation chemistry it largely initiates. Much effort is focussed on the reduction of surface levels of ozone owing to its health impacts but recent efforts to achieve reductions in exposure at a country scale have proved difficult to achieve due to increases in background ozone at the zonal hemispheric scale. There is also a growing realisation that the role of ozone as a short-lived climate pollutant could be important in integrated air quality climate-change mitigation. This review examines current understanding of the processes regulating tropospheric ozone at global to local scales from both measurements and models. It takes the view that knowledge across the scales is important for dealing with air quality and climate change in a synergistic manner.

Abstract. Ozone holds a certain fascination in atmospheric science. It is ubiquitous in the atmosphere, central to tropospheric oxidation chemistry, yet harmful to human and ecosystem health as well as being an important greenhouse gas. It is not emitted into the atmosphere but is a byproduct of the very oxidation chemistry it largely initiates. Much effort is focused on the reduction of surface levels of ozone owing to its health and vegetation impacts, but recent efforts to achieve reductions in exposure at a country scale have proved difficult to achieve owing to increases in background ozone at the zonal hemispheric scale. There is also a growing realisation that the role of ozone as a short-lived climate pollutant could be important in integrated air quality climate change mitigation. This review examines current understanding of the processes regulating tropospheric ozone at global to local scales from both measurements and models. It takes the view that knowledge across the scales is important for dealing with air quality and climate change in a synergistic manner. The review shows that there remain a number of clear challenges for ozone such as explaining surface trends, incorporating new chemical understanding, ozone-climate coupling, and a better assessment of impacts. There is a clear and present need to treat ozone across the range of scales, a transboundary issue, but with an emphasis on the hemispheric scales. New observational opportunities are offered both by satellites and small sensors that bridge the scales.

“…In Northeast Asia, which includes South Korea, BEIS3 is rarely used because it relies on the Biogenic Emissions Land Cover Database Version 3, which is only available for the North American region. Thus, many studies in Northeast Asia have used MEGAN instead [17][18][19][20][21][22]. MEGAN often over-estimates isoprene emissions compared with BEIS3 [15,23].…”

Abstract:In this study, we examined how modeled ozone concentrations respond to changes in anthropogenic emissions when different modeled emissions of biogenic volatile organic compounds (BVOCs) are used. With biogenic emissions estimated by the Model of Emissions of Gases and Aerosols from Nature (MEGAN) and the Biogenic Emissions Inventory System Version 3 (BEIS3), the Community Multi-scale Air Quality with the High-order Direct Decouple Method (CMAQ-HDDM) simulations were conducted to acquire sensitivity coefficients. For the case study, we chose 17-26 August 2007, when the Southern Korean peninsula experienced region-wide ozone standard exceedances. The results show that modeled local sensitivities of ozone to anthropogenic emissions in certain NO x -saturated places can differ significantly depending on the method used to estimate BVOC emission, with an opposite trend of ozone changes alongside NO x reductions often shown in model runs using MEGAN and BEIS3. Findings of increased ozone concentrations with one model and decreased ozone concentrations with the other model implies that estimating BVOCs emissions is an important element in predicting variability in ozone concentration and determining the responses of ozone concentrations to emission changes, a discovery that may lead to different policy decisions related to air quality improvement. Quantitatively, areas in the 3-km modeling domain that experienced daily maximum one-hour ozone concentrations greater than 120 ppb (MDA1O3) showed differences of over 20 ppb in MDA1O3 values between model runs with MEGAN and BEIS3. For selected monitoring sites, the maximum difference in relative daily maximum eight-hour ozone concentrations (MDA8O3) response between the methods to model BVOCs was 4.2 ppb in MDA8O3 when we adopted a method similar to the Relative Reduction Factor used by the US Environmental Protection Agency (EPA).
