Stable nitrogen isotopic signatures reveal the NH4+ evolution processes in pollution episodes in urban southwestern China

Wei Guo et al.

Summary: In most urban atmospheres, the formation of ammonium (NH4+) is primarily controlled by the initial isotope value of ammonia (delta N-15-NH3 values) and the corresponding ammonia conversion ratio (NH4+/(NH4+ + NH3)). NH3 sources are influenced by agricultural emissions, fossil fuel-related NH3 emissions, and biomass combustion sources, with NH3 conversion ratios playing a key role in the formation of NH4+ during pollution episodes.

Direct and cross impacts of upwind emission control on downwind PM2.5 under various NH3 conditions in Northeast Asia

Eunhye Kim et al.

Summary: This study investigated the impact of upwind PM2.5 precursor controls on downwind PM2.5 concentrations, finding that cross impacts play a crucial role in determining the overall changes in PM2.5 levels.

Improved Estimates of Ammonia Emissions from Global Croplands

Xiaoying Zhan et al.

Summary: The study improved estimates of crop-specific NH3 emissions globally and highlighted the potential impact of improving fertilization schemes in reducing global cropland NH3 emissions by three-quarters. It also identified that a small proportion of global harvested areas, primarily in China, India, and Pakistan, have the potential to contribute to 64% of emissions reduction.

Contributions of international sources to PM2.5 in South Korea

Naresh Kumar et al.

Summary: Chinese anthropogenic emissions have a significant impact on air quality in South Korea, with contributions reaching up to 60% in some months. The contribution from China to PM2.5 concentrations in South Korea was estimated to be around 45% in 2016, showing a slight decrease compared to 2015.

Co-benefits of reducing PM2.5 and improving visibility by COVID-19 lockdown in Wuhan

Liquan Yao et al.

Summary: The study suggests that government efforts to alleviate PM2.5 pollution are insufficient, and COVID-19 lockdown measures reduced PM2.5 and increased visibility in Wuhan. The reduction of NH4NO3 and PM2.5 mass were the main reasons for the improvements in air quality.

Chemical Fingerprints for PM2.5 in the Ambient Air near a Raw Material Storage Site for Iron Ore, Coal, Limestone, and Sinter

Kavita Justus Mutuku et al.

Summary: The study compared the concentrations and chemical fingerprints of resuspended and ambient air PM2.5 at a raw material storage site for iron ore, coal, limestone, and sinter. Seasonal variations were observed in the PM2.5 concentrations, compositions, and chemical fingerprints in the four sites under investigation. Water-soluble ions were found to be the most important component in all sites, with different dominant components in the various raw material piles.

Multi-model intercomparisons of air quality simulations for the KORUS-AQ campaign

Rokjin J. Park et al.

Summary: The KORUS-AQ study conducted in 2016 aimed to understand air quality factors in South Korea through extensive aircraft and ground observations. Models evaluating against these observations showed successful reproduction of certain pollutants, but systematic biases for carbon monoxide. Stratospheric ozone influxes and missing carbon monoxide sources in East Asia were identified as contributing factors to model-observation discrepancies. Ongoing model development and evaluation, along with emissions inventory improvements, are necessary for better air quality forecasting.
