Summary: The increasing energy demand and pollution have led to the rise of bioenergy plantations, with poplar being a significant source of green energy. However, it is important to consider the emissions of isoprene from poplar plantations, as it can have a long-term impact on atmospheric chemistry and climate change. Further research is needed to assess the effects and consider alternative low-emitting species for bioenergy plantations.

Summary: The GEOS-Chem model was used to compare the impacts of isoprene and iodine emissions on present-day tropospheric composition. Removing isoprene emissions leads to a 3.4% decrease in tropospheric O-3 burden, while removing iodine emissions leads to a 5.9% increase. Isoprene has a substantial impact on global mean OH concentrations and methane lifetime, while iodine has a negligible impact. It is suggested that iodine should receive greater attention in model development and experimental research to improve predictions of tropospheric O-3.

Summary: The impact of biogenic emissions from urban landscapes on ozone and SOA has been largely ignored. Including urban isoprene in the model improves the simulations of isoprene concentrations and its diurnal cycle. Urban BVOC emissions play vital roles in modulating ozone formation and will become more important in the future. Biogenic-induced SOA accounts for 16% of total SOA in urban areas.

Summary: There has been no prior research on the range of sites, potential yield, and financial characteristics of poplar short rotation coppice plantations in Hungary. A model presented in this paper suggests that these plantations have the potential for profitable financial performance, with considerations for break-even points and wood chip prices. Industrial poplar plantations have longer rotation periods and higher returns, while short rotation coppice plantations offer more evenly distributed cash flow. Expanding the application of poplar short rotation coppice may require specific subsidies and an extension of the rotation cycle beyond the current 15 years limit.

Summary: Current air quality and climate models have large uncertainties in simulating biogenic volatile organic compounds (BVOCs), primarily due to differences in the treatment of physical and chemical processes and errors in vegetation type specification. The study found that different versions of the model exhibit varying performance in simulating BVOCs emissions, with MEGAN v3.0 showing the largest amount of biogenic isoprene emissions over eastern China. Factors such as temperature and leaf area index (LAI) play a significant role in the seasonal variation of BVOC emissions.

Summary: This study evaluates the change in surface ozone (O-3) concentrations due to climate change over South America and Africa. The results show that while models predict a decrease in surface O-3 due to climate change on average, an ozone-climate penalty may occur in areas with high O-3 concentrations, such as urban and biomass burning areas.

Summary: Tree radial growth shows long-term adaptation and rapid responses to climate, with age-dependent low-frequency signals and climate-sensitive high-frequency signals. The iterative growth model (IGM) provides theoretical indicators to evaluate or predict growth by linking organism lifespan, growth rate, and respiration. This study extended the IGM to the tree-ring scale (IGMR) and found that low-frequency growth signals in poplar plantations on the Tibetan Plateau follow a unimodal pattern over the diameter at breast height (DBH) gradient while constraining high-frequency signals. The resulting indicators of growth, such as maximum DBH, growth rate, and tree lifespan, are important for assessing and predicting tree growth and forest carbon sequestration.

Summary: By combining observations and simulations, we assessed the trends of tropospheric ozone over Southeast Asia from 2005 to 2016. The surface ozone levels in Peninsular Southeast Asia showed rapid increases, primarily driven by local emissions, while the Maritime Continents experienced relatively slower increases. It is necessary to quantify Southeast Asian emissions more accurately to improve air quality management.

Summary: The study used the TM5-FASST tool to examine the impact of abatement policies on O3 and PM2.5 exposure and associated mortality. It found that O3 exposure within the UNECE area is more sensitive to measures outside the UNECE region than PM2.5 exposure, although the latter leads to higher mortality. The analysis also confirmed that abatement measures in line with UN Sustainable Development Goals and the Paris Agreement can lead to significant co-benefits between air quality and climate policies.

Summary: This study focuses on improving the representation of PM episodes in the Berlin agglomeration area using test-case studies with the LOTOS-EUROS CTM. The mixing layer height (MLH) is identified as a major impact factor, and applying the COSMO-CLM model significantly improves the meteorological representation of the PBL and MLH. A multi-level approach excluding the MLH leads to a considerable increase in the total PM mass concentration amount.

Summary: This study investigated the effects of nitrogen deposition and drought on gross primary production in European forest ecosystems, finding a varied response of forests to these factors with no consistent influence of nitrogen deposition on forest productivity during drought. This suggests that nitrogen deposition, while impacting forest productivity, is not a major driver of forest responses to drought in European forest ecosystems.

Summary: This study compared two different methods for attributing particulate matter concentrations to different sources. The results showed that the contributions from biomass and total combustion were consistent between the two methods, but the model had difficulties representing traffic emissions. Additionally, the modeled particulate matter concentrations underestimated the observed concentrations and were closely related to the contributions from combustion and secondary particulate matter.

Summary: Ammonia is a significant pollutant emitted from agricultural activities, causing harm to human health and biodiversity loss. However, current ammonia emission inventories do not account for spatial and temporal variabilities caused by weather variations and factors like manure properties and application techniques. This study proposes a method using the ALFAM2 model to derive spatially explicit slurry application emission fractions, which significantly improves ammonia emission modeling and is crucial for studying temporal variability between years.

Summary: This study investigated the changes in nitrogen dioxide (NO2) air pollution levels and their disparities in California, U.S. during the pandemic of coronavirus disease 2019 (COVID-19). The results showed a decrease in NO2 concentrations, especially in urban and high-traffic areas. However, socially vulnerable populations still experienced higher levels of NO2 exposure. The study suggests that reducing NO2 disparities, particularly racial inequity, can be achieved through continued regulatory actions targeting traffic-related NOx emissions.

Summary: This study investigates the chemical composition and oxidative potential of PM10 particles in the Po Valley, Italy, and demonstrates the impact of high levels of atmosphere ammonia. The rural area had significantly higher ammonia concentrations compared to the urban site, resulting in higher levels of secondary inorganic aerosol. Although the SIA components did not contribute significantly to the PM10 oxidative reactivity, they were correlated with the oxidative potential measurements. This suggests that the contribution of SIA to PM oxidative toxicity cannot be ignored.
