“…We refer the reader to Jiang et al (2015b) for more details about the application and evaluation of TES O 3 data. An obvious feature is the low O 3 concentrations over the maritime continent and the Amazon, which is consistent with previous studies using measurements from satellite, ozonesonde and aircraft (Rex et al, 2014;Bela et al, 2015). Over the northern middle latitudes, O 3 concentrations are highest in summer.…”

Abstract. Significant progress has been made in identifying the influence of different processes and emissions on the summertime enhancements of free tropospheric ozone (O 3 ) at northern midlatitude regions. However, the exact contribution of regional emissions, chemical and transport processes to these summertime enhancements is still not well quantified. Here we focus on quantifying the influence of regional emissions on the summertime O 3 enhancements over the Middle East, using updated reactive nitrogen (NO x ) emissions. We then use the adjoint of the GEOS-Chem model with these updated NO x emissions to show that the global total contribution of lightning NO x on middle free tropospheric O 3 over the Middle East is about 2 times larger than that from global anthropogenic sources. The summertime middle free tropospheric O 3 enhancement is primarily due to Asian NO x emissions, with approximately equivalent contributions from Asian anthropogenic activities and lightning. In the Middle Eastern lower free troposphere, lightning NO x from Europe and North America and anthropogenic NO x from Middle Eastern local emissions are the primary sources of O 3 . This work highlights the critical role of lightning NO x on northern midlatitude free tropospheric O 3 and the important effect of the Asian summer monsoon on the export of Asian pollutants.

“…Although there are a number of studies involving the measurements of atmospheric pollutants in the Amazon region (e.g., Kuhn et al, 2010;Trebs et al, 2012;Baars et al, 2012;Artaxo et al, 2013), most of the contribution was published very recently with the results of the GoAmazon2014/5 project Alves et al, 2016;Pöhlker et al, 2016;de Sá et al, 2017;Kourtchev et al, 2016;Hu et al, 2016;Bateman et al, 2017;Cecchini et al, 2016;Jardine et al, 2016). In terms of numerical studies, only a few studies focusing the role of the anthropogenic emission sources in urban areas are available Andreae et al, 2012;Beck et al, 2013;Bela et al, 2015). These studies do not address the participation of each type of emission source on air pollutants, which is important for the formulation of regulatory public policies for air quality management.…”

Abstract. This paper evaluates the contributions of the emissions from mobile, stationary and biogenic sources on air pollution in the Amazon rainforest by using the Weather Research and Forecasting with Chemistry (WRF-Chem) model. The analyzed air pollutants were CO, NO x , SO 2 , O 3 , PM 2.5 , PM 10 and volatile organic compounds (VOCs). Five scenarios were defined in order to evaluate the emissions by biogenic, mobile and stationary sources, as well as a future scenario to assess the potential air quality impact of doubled anthropogenic emissions. The stationary sources explain the highest concentrations for all air pollutants evaluated, except for CO, for which the mobile sources are predominant. The anthropogenic sources considered resulted an increasing in the spatial peak-temporal average concentrations of pollutants in 3 to 2780 times in relation to those with only biogenic sources. The future scenario showed an increase in the range of 3 to 62 % in average concentrations and 45 to 109 % in peak concentrations depending on the pollutant. In addition, the spatial distributions of the scenarios has shown that the air pollution plume from the city of Manaus is predominantly transported west and southwest, and it can reach hundreds of kilometers in length.

Dry deposition of ozone is an important sink of ozone in near‐surface air. When dry deposition occurs through plant stomata, ozone can injure the plant, altering water and carbon cycling and reducing crop yields. Quantifying both stomatal and nonstomatal uptake accurately is relevant for understanding ozone's impact on human health as an air pollutant and on climate as a potent short‐lived greenhouse gas and primary control on the removal of several reactive greenhouse gases and air pollutants. Robust ozone dry deposition estimates require knowledge of the relative importance of individual deposition pathways, but spatiotemporal variability in nonstomatal deposition is poorly understood. Here we integrate understanding of ozone deposition processes by synthesizing research from fields such as atmospheric chemistry, ecology, and meteorology. We critically review methods for measurements and modeling, highlighting the empiricism that underpins modeling and thus the interpretation of observations. Our unprecedented synthesis of knowledge on deposition pathways, particularly soil and leaf cuticles, reveals process understanding not yet included in widely used models. If coordinated with short‐term field intensives, laboratory studies, and mechanistic modeling, measurements from a few long‐term sites would bridge the molecular to ecosystem scales necessary to establish the relative importance of individual deposition pathways and the extent to which they vary in space and time. Our recommended approaches seek to close knowledge gaps that currently limit quantifying the impact of ozone dry deposition on air quality, ecosystems, and climate.
