Summary: The warming Arctic Ocean and sea ice retreat have significant impacts on the marine biogenic sulfur cycle, but the effect of dimethyl sulfide (DMS) chemistry on atmospheric aerosols in the high Arctic Ocean is still unclear. This study investigated the DMS chemistry in the Arctic Ocean and Pacific Ocean, revealing significant spatial variation in particulate methanesulfonic acid (MSA) concentrations and the dominance of sea salt aerosols in the high Arctic Ocean. The results contribute to our understanding of the role of DMS chemistry in atmospheric aerosols and its impact on the regional atmosphere in the Arctic Ocean.

Summary: The study demonstrates the harmful impact of Black Carbon on the Arctic environment and identifies a major transport pathway for Black Carbon from lower latitudes into the Arctic, reaching the high Arctic in as little as 7 days. The measurement sites and transportation pathways studied are found to be representative of the Arctic as a whole.

Summary: Aerosol-climate interactions are important in the Arctic, exhibiting large spatiotemporal variability. Current climate models do not capture the complex local processes and feedbacks, highlighting the need for further research on natural aerosol evolution and impacts.

Summary: This study explores the long-term properties of cirrus clouds for the first time over an Arctic site, finding that cirrus clouds are generally associated with colder and calmer wind conditions, but their properties do not strongly depend on temperature and wind speed, with wintertime cirrus appearing thicker and with more spherical ice particles. The majority of cirrus at the Arctic site are associated with westerly flow and tend to be optically thicker and consist of more spherical ice particles compared to lower latitudes.

Summary: The study evaluated the vertical distribution of Arctic aerosols using data from a tethered balloon system over multiple seasons. It found that ground-based aerosol number concentrations were often unequal to those at cloud base, with intermittent aerosol layers observed due to poorly mixed below-cloud environments. The potential temperature profiles of the below-cloud environment reflected the aerosol profile in most cases, indicating a complex interplay between aerosol sources, thermodynamic structure, and wet removal processes.

Summary: A new retrieval algorithm called AEROIASI-H2SO4 was developed to measure the extinction and mass concentration of sulphate aerosols based on IASI observations. The algorithm shows moderate random uncertainties and accurately identifies the volcanic plume horizontal morphology, providing crucial new information towards the study of volcanic emissions. Insights are given on the possible spectroscopic evidence of the presence of larger-sized particles in the plume.

Summary: Analyzing lightning activity data from two different regions in the Arabian Peninsula, this study found that aerosols have varying impacts on lightning activity, with a trend of reversal. The mountainous region showed a stronger correlation compared to the inland region. Both regions exhibited seasonal and asynchronous changes in lightning activity and aerosol loading.

Summary: The study investigated the effects of shipping aerosols on radiation, cloud physical properties, and precipitation, finding that the indirect effect of shipping aerosols has a more significant impact on clouds. Through their direct and indirect effects, shipping aerosols cause non-negligible impacts on precipitation, with significant changes in low cloud coverage.

Summary: This study investigates the impact of mid-latitude pollution inflow on aerosol-cloud-radiation interactions during an episode of extreme warm-air advection. Elevated turbulent clouds were found to be more sensitive to aerosol variations compared to stably stratified fog layers. Omission of either anthropogenic or biomass burning sources resulted in decreased cloud liquid water and cloud droplet concentrations, but did not substantially modify the net surface radiation budget.

Summary: Characterizing the optical properties of aerosols is important for understanding their role in ecosystems and climate. This study provides long-term measurements of aerosol optical properties in the Brazilian Pantanal region, showing the effects of biomass burning emissions on absorption and scattering. Brown carbon is found to have a significant contribution during the dry season.

Summary: The study shows that primary biological aerosol particles (PBAP) in different sectors of the Southern Ocean (SO) mainly come from sea spray aerosol (SSA) particles, with fluorescent PBAP and hyper-fluorescent PBAP contributing 1.6% and 0.13% to super-micrometer SSA respectively. Marine biota concentrations modulate the PBAP source flux.

Summary: This study investigated the BSOA tracers in the atmosphere of the Arctic Ocean and found differences in the sources of precursors for different BSOA. The oxidation of monoterpenes contributed more to secondary organic carbon than isoprene, and sea ice changes had a relatively small effect on biogenic SOC concentration levels.

Summary: Aerosols play a crucial role in the Earth-atmosphere system, and this study investigates the physical and optical properties of marine aerosols in the South China Sea. Observations show that aerosols are concentrated at lower altitudes, and the extinction coefficient reaches its maximum value. Meteorological factors have significant impacts on aerosol properties. Long-term analysis reveals that AOD decreases with the distance from the continent, with higher values in spring and winter. Sulfate and sea salt dominate the aerosol compositions in this region.
