Summary: The bushfires in Australia in late 2019 and early 2020 were unprecedented in scale and intensity. This study analyzed the NO2 and CO emissions using satellite data and found significant variations in different vegetation types. The findings contribute to understanding the impact of biomass burning on regional air quality and can be applied to other large fires and fossil fuel burning in megacities.

Summary: This study investigates the response of tropical forests to climate change impacts. The research finds that under low emissions scenarios, the biomass of the Amazon tropical forest will increase, but under high emissions, fires will lead to forest loss and hinder recovery. Furthermore, the study reveals that current climate conditions of drought and decreased precipitation intensify the occurrence of fires.

Summary: This study questions the importance of local and large-scale processes on the dynamics of fire in the subalpine belt in the western Alps. The results show that climate is the main driver of fire occurrence, while local conditions play a minimal role in determining variability at the century scale. The mid-Holocene was a key period for climate-driven biomass burning, while fires during the late Holocene appear to be more episodic, suggesting the influence of human activity.

Summary: The authors discussed the potential of using Google Trends data to anticipate future trends, with a focus on the 2019 Amazon fires. They found a correlation between the President of Brazil's speeches and specific keywords with the increase in fire outbreaks, highlighting the possible influence of political figures on environmental events. Additionally, the study revealed a strong relationship between Google Trends keywords related to Germany and fires in the Amazon region, indicating potential international implications for the environmental crisis.

Summary: Using satellite data and aircraft monitoring, this study confirms a 54% decrease in deforestation-related CO emissions in the Amazon Basin over the past 16 years. The study also found significant interannual variability, with fire emissions in dry years being more than four times higher than in wet years. Additionally, the study highlights that future carbon release from fires depends on both drought intensity and forest protection.

Summary: Biomass burning particulate matter (BBPM) has significant impacts on air quality and climate, and this impact is expected to increase in the future. Studies have shown that the concentration of BBPM from North American fires is dependent on altitude, with airborne and high-altitude measurements showing a doubling of BBPM compared to ground-based measurements. The volatility of BBPM partially explains the observed differences in concentration across platforms.

Summary: This study analyzed the relationship between mesoscale convective system and biomass burning aerosol during the dry season of 2014. The results showed that biomass burning aerosol weakens the intensity of the convective system and reduces the vertical and horizontal transport of carbon monoxide and ozone. In the absence of biomass burning aerosol, downdrafts and precipitation rate are more intense, and cloud development is more significant, resulting in stronger horizontal flow and vertical transport of ozone, but more efficient in reducing the concentrations of other gases.

Summary: The oxidation of polycyclic aromatic hydrocarbons (PAHs) determines their lifetime, toxicity, and environmental impact. The oxidation rate of PAHs is influenced by the mixing state of particles. Larger PAHs with substantial amounts of black carbon (BC) internally mixed with organic aerosol (OA) were rapidly oxidized under solar radiation, while larger PAHs with externally mixed OA tended to remain unmodified during the evolution.

Summary: Drought and fire reduce productivity and increase tree mortality in tropical forests. Fires produce pyrogenic carbon (PyC), which improves soil fertility and water holding capacity and selects for tree species capable of growing during droughts. This study found that forests with higher concentrations of soil PyC had higher soil fertility, lower wood density, and were more resistant to severe drought. Forests with a legacy of ancient fires had higher carbon gains during droughts compared to forests with low soil PyC concentrations. This suggests that past fires have a lasting impact on current forest dynamics and resilience to drought.

Summary: Experiments were conducted to investigate flame acceleration and deflagration-to-detonation transition (DDT) in ethanol-air mixtures using a tube filled with orifice plates at different initial temperatures and pressures. It was found that DDT occurred in mixtures with equivalence ratios of 1.1-1.3 at 101 kPa, but not at 60 kPa. By analyzing the data of ethanol-air mixtures with a double cell structure, it was determined that the DDT limit is correlated with the large-cell size of ethanol, suggesting the importance of using large-cell size data for assessing DDT potential.

Summary: Unconventional oil and natural gas development (UOGD) in the United States has expanded rapidly in recent decades, raising concerns about its impact on air quality. This study conducted extensive air monitoring during the development of several large well pads in Broomfield, Colorado, providing a unique opportunity to examine changes in local air toxics and VOC concentrations during well drilling and completions and production. The study identified significant increases in VOC concentrations during drilling operations, highlighting the importance of emissions from synthetic drilling mud. The findings suggest opportunities to mitigate emissions during UOGD operations.

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.

Summary: Accurate measurement of atmospheric reactive mercury is challenging due to its reactivity and low concentrations. The University of Nevada, Reno Reactive Mercury Active System (RMAS) has been shown to be more accurate than the industry standard, but has limitations including long time resolution and sampling biases. Increasing the sampling flow rate negatively affected RM concentrations, but did not impact the chemical composition of RM captured on membranes.

The accuracy of the models varied across regions, with the ME models exhibiting higher predictions and lower biases. The use of region-specific microenvironmental measurements in the ME model showed potential for accurate prediction of personal PM2.5 exposure.

Summary: This study developed a sensitive method to measure the metallic components of atmospheric fine particulate matter (PM2.5) and compared the results with different analysis methods. The concentrations of metallic components in personal PM2.5 samples were found to be significantly different from corresponding fixed-site samples. Personal sampling can reduce exposure misclassifications, and measuring metallic components is useful for exploring health risks and identifying sources of PM2.5.

Summary: Increasing concentrations of microplastics in the Earth's atmosphere could have adverse effects on ecosystems and human health. The deposition rate of airborne microplastics is influenced by both land use and climate, and a global analysis suggests that climate may have a greater impact on the concentration and deposition rate of microplastics than land use.
