Summary: Recent studies have shown that the Asian summer monsoon anticyclone transports emissions from rapidly industrializing nations into the upper troposphere, affecting ozone-depleting substances (ODSs) concentrations. Measurements from air samples collected during the summers of 2016 and 2017 revealed higher than expected levels of ODSs, including chlorinated very short-lived substances. Trajectory analysis indicated South Asia as a possible source region for some ODSs. These findings suggest a potential impact on the stratospheric ozone layer.

Summary: While previous studies have suggested the role of ozone-depleting substances (ODSs) in historical climate change, their contribution to anthropogenic warming has not been quantified. Using a state-of-the-art Earth System Model, this study found that ODSs are responsible for 30% of global warming, 37% of Arctic warming, and 33% of summertime Arctic sea ice loss over the 1955-2005 period. The study also highlighted that the global warming response to ODSs per unit of Effective Radiative Forcing (ERF) is about 20% larger than for CO2, emphasizing the importance of the Montreal Protocol for mitigating future climate change.

Summary: After the 2020 Australian bushfires, satellite observations documented stratospheric aerosol, temperature, and ozone anomalies in the Southern Hemisphere. The anomalies were comparable to the effects of the Calbuco eruption in 2015, with enhanced aerosols and warm temperature anomalies leading to midlatitude ozone depletion. The overall effects resembled those of the 2015 eruption, with record low ozone levels and polar temperatures.

Summary: Using a stratosphere-resolving general circulation model, this study examines the relative effects of stratospheric ozone and greenhouse gases (GHGs) on the temperature and circulation in the Arctic stratosphere. The results show that the impact of ozone increase is approximately 2 times larger than that of GHGs increase, and is closely related to the wave fluxes in the stratosphere.

Summary: This study estimates the HCFC-141b emissions in eastern China from 2000-2019 and predicts the emissions from 2020-2050 under different scenarios. The results show an increasing trend in HCFC-141b emissions in eastern China, with a significant potential for reduction under the Montreal Protocol and accelerated phase-out scenarios. The findings highlight the importance of phasing out HCFC-141b for ozone layer protection and climate change mitigation.

Summary: Chloromethanes, including mono, di, tri, and tetrachloromethane, contribute to stratospheric ozone depletion. This study established a plant-scale inversion system to quantify the emission factors of chloromethanes from chloromethane production plants. The method developed in this study provides valuable insights for accurately assessing the impact of chloromethanes on the ozone layer.

Summary: Irrigation can both cool and warm air temperature depending on the balance between daytime cooling and nighttime warming. Evaporative cooling and reduced solar radiation during the daytime can lower air temperature, while the increased atmospheric water vapor at night can enhance the local greenhouse effect and increase nighttime temperature. It is important to consider sub-daily processes when assessing the impact of irrigation on daily air temperature and temperature-related socioeconomic phenomena.

Summary: Studies suggest that increasing CFC-11 emissions lead to a deepened ozone hole, affecting atmospheric circulation and temperature distribution in the Antarctic lower stratosphere. However, the age of air is slightly younger in high emission scenarios, and the greenhouse gas impact of CFC-11 is minimal and not statistically significant in both the troposphere and stratosphere.

Summary: Temperature trends in the upper stratosphere are examined using satellite measurements and simulations from climate models. Observational evidence reveals a lack of cooling in the Antarctic during austral winter over a specific period, while simulations over a longer period also show contrasting temperature trends between the Antarctic and lower latitudes. Further analysis suggests that ozone-depleting substances have contributed significantly to the lack of cooling in the Antarctic upper stratosphere.

Summary: Surface ozone, a major air pollutant, is influenced by stratosphere-troposphere exchange (STE) which contributes to both the decrease and increase of surface ozone in the Southern and Northern Hemispheres, respectively. Additionally, global warming is expected to worsen surface ozone pollution in the future.

Summary: Global and regional atmospheric measurements and modeling are crucial in identifying and quantifying unexpected emissions of environmentally important substances. This study focuses on newly discovered HCFC-132b and updates on HCFC-133a and HCFC-31, showing global emissions trends and regional enhancements. Emissions of these compounds are most likely as intermediate by-products in chemical production pathways, with East Asia being a significant contributor to global emissions.

Summary: The factors influencing the size of the Antarctic ozone hole in November are mainly dynamic processes, with weaker ozone transport related to planetary wave divergence in the stratosphere. Anomalously large ozone holes in November are not always preceded by large holes in late winter, and processes for large and small holes are generally opposite.

Summary: This study investigates changes in stratosphere-troposphere exchange (STE) of air masses and ozone concentrations from 1960 to 2099. The results show that global ozone STE decreased by 11% from 1960 to 2000, but increased by 47% from 2000 to 2099. The changes in ozone STE are mainly driven by ozone concentration changes, including climate-induced changes and ozone-depleting substance (ODS) changes.

Summary: This study investigates the interaction between orographic gravity waves (OGWs) and resolved dynamics in atmospheric models, showing that strong OGW drag events are associated with anomalous wave propagation in the stratosphere. The response of the resolved wavefield to strong OGW events depends on the region, leading to diverse consequences on the large-scale stratospheric circulation. The two-way coupling between OGWs and resolved flow highlights the complexity of atmospheric dynamics.

Summary: Despite significant reductions in emissions, summer surface ozone concentrations in Austria still exceed health protection standards. The temperature sensitivity of ozone production increases in spring and summer, and rising temperatures may offset future emission reductions. Biogenic volatile organic compounds (BVOCs) are the dominant source of hydrocarbons in urban areas during the ozone season. Decreasing anthropogenic nitrogen oxide (NOx) emissions remains the most effective short-term measure to reduce surface ozone concentrations.
