Summary: This study reports the emission characteristics of organic carbon (OC) and elemental carbon (EC) from biofuel combustion based on field measurements in rural households in Guizhou Province, China. The results show that firewood burning is the primary contributor to emissions, with higher emission factors compared to crop straw burning. Furthermore, different types of crop straw burning have varying emission characteristics of OC and EC.

Summary: This study focused on measuring the emission factors of HONO from agricultural residue open burning and establishing a high-resolution emission inventory for HONO from 2011 to 2015 in China. Results showed the average EFHONO for wheat, rice, corn and soybean straws, with total annual emissions estimated for each year. High HONO emission intensities were observed in North China Plain and Northeast China, while lower intensities were seen in western regions. Peak emissions were recorded in March, April, June, and October. The findings are expected to enhance the accuracy of HONO budgets and air quality simulations in China.

Summary: The study measured the atmospheric phosphorus emissions from burning different types of crop residues through experimental chamber tests and developed a high-resolution emission inventory for China. It found that biomass burning was an important source of bioavailable phosphorus, with different crop straw types emitting varying amounts of total P, total dissolved P, dissolved inorganic P, and dissolved organic P. The high P emission areas were concentrated in major grain production regions, with emissions peaking in months affected by crop harvesting periods. The results can provide valuable data for modeling research and improve the accuracy of estimating atmospheric P deposition.

Summary: This study assesses the differences in total particulate matter (TPM) emissions when calculated using different satellite aerosol optical depth (AOD) data. Using high spatial resolution AOD data, a 90% decrease in TPM emission coefficients (Ce) is found in Australia, and the quality of Ce improves by 290%. Using 1 km AOD data instead of 10 km AOD data, the estimation of biomass burning TPM emissions in Australia during 2012-2020 decreases from 1.08Tg to 0.11Tg.

Summary: Global emissions of methyl halides from biomass burning decreased between 2003 and 2021, except for an increase in the northern high-latitude region. Analysis showed different drivers for methyl halide emissions from different types of fires. Non-BB emissions of methyl halides also showed variations during the same period. The findings highlight the importance of identifying unknown sources and re-evaluating known sources of methyl halide emissions.

Summary: Clean air is crucial for human health and well-being, but rapid urbanization poses risks to air quality. This study presents a comprehensive GIS-based emission inventory of heavy metals and NMVOCs in Delhi, covering road transportation, road dust, and biomass burning. The findings show that heavy metal emissions are mainly from biomass burning and road dust, with Zinc being the highest contributor. Road transportation contributes the most to overall emissions, while biomass burning is a significant source of NMVOC emissions. This study provides valuable information for policymakers and stakeholders to develop effective strategies to reduce emissions and improve air quality.

Summary: Australian fires have a significant impact on atmospheric composition and carbon budgets, but the emissions from biomass burning in Australia are uncertain. This study evaluates the performance of global models and biomass burning emission inventories in simulating carbon monoxide in the Australian atmosphere using various observations. The results suggest that GFED4s is the best option for global modeling studies focusing on Australia or the Southern Hemisphere, and continuous measurements are needed to improve global biomass burning inventories.

Summary: Satellite-based post-tornado assessments have traditionally relied on visible and near-infrared channels to detect tornado tracks through identifying vegetation changes. However, this study shows that in a cropland-dominated and less vegetated area, significant scars are captured only by the shortwave infrared channels. The dominant soil type with high clay content contributes to preserving the severe changes in soil structure during tornado passages. This study suggests the use of shortwave infrared channels for quick post-tornado assessments in less vegetated areas.

Summary: Urbanization modifies the meteorological conditions for tornado formation and intensification, increasing the risk of tornadoes in the United States. In this study, it was found that urbanization may enhance tornado potential by strengthening low-level streamwise vorticity and intensifying near-surface horizontal vorticity near the cold pool boundary. These effects are mainly due to stronger outflow boundaries and better alignment of storm-relative inflow with horizontal vorticity. Further research is needed for a more comprehensive understanding of the impact of urbanization on tornado potential.

Summary: High temporal resolution aerosol optical depth (AOD) observations from new-generation geostationary satellites provide unique advantages in analyzing aerosol fast variation processes. However, a large proportion of missing data in GEO AOD products due to cloud obscuration and retrieval algorithm limits their expected advantages and values. In this study, a novel nested spatiotemporal fusion method based on the Bayesian maximum entropy theorem is developed to recover GEO Himawari-8 AHI AOD data by blending GEO with sun-synchronous orbit satellite observations.

Summary: A significant portion of precipitation in the western United States is contributed by wintertime orographic clouds associated with atmospheric rivers (ARs). This study examines the impact of ice-nucleating particles (INPs) from marine aerosols on cloud and precipitation properties during different stages of an AR event. The results show that marine INPs enhance ice and snow formation, leading to more mixed-phase and deep clouds, as well as increased precipitation after AR landfall. The effects of marine INPs vary with the AR stages, with more pronounced effects before and after AR landfall.

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.
