Summary: Sea salt aerosol particles are abundant in the atmosphere and have significant impacts on global radiative balance. However, laboratory studies on these particles often neglect the losses of solutes to the gas phase, which can lead to misinterpretation of data and errors in air quality or climate models predictions.

Summary: Researchers found that benzothiazoles in coastal waters are primarily from anthropogenic sources, and the oxidation of gas-phase benzothiazole can lead to the formation of secondary aerosols in the atmosphere, potentially contributing to the formation of secondary marine aerosols in coastal regions.

Summary: This study focuses on estimating dry marine aerosol surface area using bulk optical measurements. Two field campaigns were conducted to evaluate the estimation methods. The results show that the approximation of dry aerosol surface area based on the angstrom ngstrom exponent is valid under certain conditions, but caution is needed for different distributions. The study also proposes new lidar conversion parameters applicable to marine aerosol in the Southern Ocean.

Summary: The oceans contribute to aerosol particles in the atmosphere through sea spray aerosol (SSA) production and the emission of gases that condense to form secondary marine aerosol (SMA). These aerosol emissions include salt particles, sulfate particles, and organic components. SSA particles are mainly formed from bubbles as film drops, while SMA particles come from marine biogenic gas emissions. The impact of ocean-derived particles on climate varies by region, and efforts to quantify global SSA and SMA emissions rely on global models with limited field measurements.

Summary: The production of marine aerosols is influenced by wind speed, particularly in the Southern Ocean, where enhanced aerosol concentrations as a result of surface cooling reduce near-surface westerly jet, thus decreasing aerosol production. Research indicates that there is a feedback mechanism between the atmosphere and ocean that partially regulates the production of sea spray aerosol.

Summary: This study characterizes the composition of single-particle aerosols collected during the ORACLES and CLARIFY-2017 campaigns. The study focuses on aged biomass burning aerosol and its interaction with the marine boundary layer, as well as the influence of biomass burning air on marine aerosol. The results suggest that atmospheric processes such as photolysis, oxidation, and cloud processing play a key role in the composition and morphology of aged biomass burning aerosols.

Summary: INPs have a significant impact on cloud properties over oceans. Recent studies show that marine INPs come from two classes of organic matter in SSAs, yet current parameterizations may mask specific trends. This paper proposes a new parameterization based on field study results to better understand the connection between ocean biology and marine INP abundance.

Summary: When small bubbles rupture in contaminated water, the resulting liquid jet breaks up into droplets that can release solid particles into the air. It has previously been thought that only small particles could be transported into the top jet drop, but this study shows that larger particles can also be transported and have a greater impact. Through experiments and simulations, the researchers identify the location of the liquid that forms the top jet drop and explain how interfacial rearrangement, bubble and particle size, and particle distribution contribute to particle enrichment.

Summary: Atmospheric deposition is a major source of micronutrient trace elements in the surface ocean. This study assesses the contribution of sea spray aerosol (SSA) to aerosol trace element loading, finding that only vanadium has a significant SSA contribution. The study highlights the limitations in measuring trace elements in SSA and the potential for overestimating new trace element inputs from atmospheric deposition.

Results show changes in ozone and NO2 levels in different regions, while PM concentrations remained relatively stable. Meteorological conditions may have influenced the dispersion of PM and NO2.

Summary: Sea spray aerosols (SSAs) have a significant impact on cloud formation and atmospheric radiative balance. Quantification of the contribution of SSAs to cloud condensation nuclei (CCN) is crucial for understanding the radiative budget. This study utilizes a unique dataset to show that previous estimates of SSA-derived CCN may have been underestimated.

Summary: Icelandic topsoil sediments are the largest and most important source of mineral dust in Europe. This study designed a dynamic coupled atmosphere-dust numerical modeling system to simulate and predict the Icelandic mineral dust process and assess its impacts on air quality, human health, transportation, climate, and marine ecosystems. The model demonstrated its capability to forecast major transport features and can be used as an operational forecasting system or a tool for assessing Icelandic dust impacts.

Summary: Face masks can prevent the transmission of SARS-CoV-2, but they can also release toxic volatile organic compounds (VOCs). Surgical masks have the highest VOC emissions, but they can reach acceptable levels after natural ventilation. Children's masks have higher emissions due to colorful cartoon patterns. It takes longer for N95 respirators to remove toxic substances.

Summary: Renewable biomass is important for climate-friendly heating, but it has negative effects on local air quality due to the increase in residential heating appliances. A study found that solid-fuel residential heating haze contains firelighter smoke, which contributes additional black carbon. This combination results in high levels of submicron particulate matter and strong radiative forcing. A co-benefit policy is needed to address this issue.

Summary: We conducted in situ measurements of black carbon (BC) concentration in Chennai, India from January to June 2020. The results showed an unprecedented reduction in BC concentration during the COVID-19 lockdown, despite stronger precipitation. The study also revealed that BC depletion was more pronounced in continental air than in marine air, and there was a shift from fossil-fuel dominance to biomass burning dominance as a BC source.
