Summary: This study evaluates the accuracy of the DOMINO product from OMI by comparing it with ground-based MAX-DOAS instruments in the Mexico City Metropolitan Area. The differences observed between OMI and MAX-DOAS VCDs are attributed to reduced sensitivity of the satellite product near the surface. However, improvements in the linear regression slopes at individual sites are observed after smoothing the MAX-DOAS profiles.

Summary: India's rural areas, where 67% of the population resides, play a crucial role in the country's future development. This study on rural air quality reveals that NO2 pollution in these regions is as significant as in urban areas. Road transport is the main source of NO2 pollution in rural India, highlighting the need for effective measures to reduce population exposure and protect public health.

Summary: A novel method is applied in this study to directly use satellite data to evaluate the spatial patterns of urban NOx emissions inventories. The results show that the 108 spatial surrogates used by NEMO are generally appropriate, but there may be underestimation in areas with dense intermodal facilities and overestimation in wealthy communities.

Summary: This study examines the spatio-temporal patterns of nitrogen dioxide (NO2) concentrations in different land cover types across California from 2009 to 2020. The results show that NO2 concentrations continue to decline in urban areas, but are insignificant or rapidly increasing in rural regions, particularly in remote forests. The study also finds that rising temperatures and decreasing precipitation due to climate change contribute to increased soil NOx emissions, explaining a third of the observed NO2 rise in non-urban regions. Furthermore, the rise in wildfire frequency since the 21st century is attributed to the trends or their absence.

Summary: Satellite measurements show consistent increase in ozone levels across the Asia-Pacific region, with most regions transitioning to NOx-limited ozone chemistry while some major cities still experience NOx-saturated conditions. Short-term VOC and NOx controls are needed to reduce ozone levels. IPCC predicts that NOx saturation will continue until 2025, with a gradual shift to NOx-limited regimes by 2050. Continued reductions in NOx emissions will be crucial for long-term ozone reduction.

Summary: Nitrogen oxides (NOx) are significant air pollutants with a crucial role in atmospheric chemistry. A comparison between Ozone Measuring Instrument's (OMI) NO2 records and in-situ surface measurements from the US Environmental Protection Agency and Texas Commission on Environmental Quality network was conducted to understand the relationship between satellite and surface observations and identify potential synergies. The analysis showed a correlation (r) ranging from 0.2 to 0.8 between daily surface site observations and OMI data, which improved significantly for monthly averages. The study also revealed significant reductions in NO2 levels in highly populated cities and urban centers, while oil and gas producing regions experienced an increase during the studied period. In addition, temporary reductions in NO2 levels were observed in major cities of Texas during the COVID-19 pandemic, surpassing previous records and indicating the potential of technological advancements in reducing NOx emissions.

Summary: Nitrogen oxides (NOx) are important air pollutants that have been examined using satellite and in situ surface observations. In Texas, there were significant reductions in NO2 levels in highly populated cities, but increases in oil and gas producing regions. COVID-19 travel restrictions led to a temporary but larger reduction in NO2 levels compared to previous years, highlighting the potential for technological advancements to reduce NOx emissions.

Summary: The models show reduced aerosol amounts in 2020, particularly over southern and eastern Asia, leading to increased surface shortwave radiation levels. However, the impact on near-surface temperature or rainfall during 2020-2024 is extremely small and not detectable in this initial analysis. Further regional analyses and closer attention to extremes are needed to evaluate the impact of COVID-19-related emission reductions on near-term climate.

Summary: In low- and middle-income countries, socioeconomic development has led to increased emissions of air pollutants, such as nitrogen oxides, which impact human health. However, in Africa's northern biomass-burning region, decreasing burned area and increasing GDP density have led to reductions in tropospheric NO2 levels during the dry season, showing a unique pathway for potential air quality benefits. This suggests that economic development can play a role in mitigating air pollution during highly polluted months.

Summary: Smallholder farmers in sub-Saharan Africa struggle to achieve food security, and it is crucial to find practices that enhance crop production without significantly increasing greenhouse gas emissions. Common practices like expanding agricultural land, developing water irrigation techniques, and increasing fertilizer use may lead to trade-offs between food security and GHG mitigation. An integrated land-water-nutrient management strategy is needed to address these challenges and ensure sustainable crop production.

Summary: COVID-19 pandemic responses have impacted atmospheric composition and climate. The effects of these responses depend on various factors such as background emissions, climate, and the season in which lockdowns occur. Multiple scenarios were used to evaluate atmospheric and climate impacts, with differences in aerosols and trace gases observed across different decades and seasons. Regional anomalies in atmospheric composition were largest when emissions were near historical peaks, and aerosol direct effect anomalies varied across different regions and time periods.

Summary: Eastern Africa experiences bimodal rainfall with long rains and short rains, and changes in rainfall have significant socioeconomic and environmental impacts. Teleconnections like El Nino-Southern Oscillation and the Indian Ocean Dipole play a major role in interannual variability. The long rains have been getting drier while the short rains have become wetter. These patterns affect flooding, droughts, food and energy systems, diseases, and ecosystem stability. Climate projections suggest that by 2030-2040, the short rains will deliver more rainfall than the long rains, posing challenges for agriculture and public health emergencies. Mitigation efforts should focus on agriculture, clean water, medical and emergency infrastructure, and adaptation strategies.

Summary: Ammonia plays a crucial role in the chemistry of inorganic secondary aerosols in the atmosphere, with agriculture being the largest source of ammonia emissions. This study evaluates different approaches to simulate ammonia emissions from agriculture and assesses the model performance using global in situ observations. The results show that different emission inventories and simulation methods perform similarly in capturing the geographical patterns of ammonia emissions, but have varying performance in data-scarce regions. The study also highlights the importance of considering meteorological variability and biogeochemical cycles in ammonia emissions modeling.

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.
