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: Inland transported sea spray aerosol (SSA) particles play a crucial role in the regional circulation of nitrogen, sulfur, and halogen species in the atmosphere. Organic coatings on SSA particles can significantly affect the chloride depletion mechanisms during long-range transport, with organic acids estimated to occupy up to 34% of the chloride depletion. Different degrees of chloride depletion were observed between SSA-Aged and SSA-Bio particles, with organic coatings likely inhibiting displacement reactions between acids and chloride.

Summary: This study examines the ability of marine boundary layer aerosol particles to act as ice-nucleating particles (INPs) in typical mixed-phase and cirrus cloud conditions. Results show that these particles can serve as INPs, providing insights for the implementation of ice crystal formation parameterizations in cloud and climate models.

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: This study proposes a mechanistic sea spray generation function based on the physics of bubble bursting. By considering key physical parameters such as wind speed, sea state, and water temperature, the mechanism of sea spray formation is described. The resulting function shows remarkable coherence with observations, highlighting its importance in understanding the mechanism of sea spray generation.

Summary: Laboratory measurements were conducted to study the characteristics of droplet size, velocity, and accelerations generated by mechanically and wind-forced water breaking waves. The results showed that the droplet size distribution followed power laws, and the velocity and acceleration distributions were found to be asymmetric.

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: Various types of virus particles have been found to nucleate ice, with a minor contribution to the atmospheric ice-nucleating particle population in the terrestrial-influenced atmosphere, but potentially important in the remote marine atmosphere. Further research on different types of viruses is needed to understand their ice-nucleating potential and mechanism.

Summary: This study conducted combined hygroscopic growth measurements using SPRM-ARI and HTDMA to investigate the relationship between the hygroscopic properties of individual particles and the bulk hygroscopic growth and chemical composition of atmospheric aerosols. Based on the measurements using SPRM-ARI, the individual particles were classified into non-hygroscopic, less hygroscopic, and more hygroscopic categories. These findings are important for a better understanding of the impact of aerosols on regional radiation, cloud formation, and climate.
