Summary: This study utilized the Weather Research and Forecasting model coupled with chemistry to simulate dust episodes during a field campaign in April 2012. The model successfully predicted dust occurrences, transport, and structure, but had discrepancies in simulating AOD and AE. Model concentrations were overestimated for larger particles and underestimated for smaller particles compared to observations.

Summary: A source-oriented Community Multiscale Air Quality model was used to study the contributions of different sources to ground-level fine particulate matter (PM2.5) and ozone (O-3) over the Yangtze River Delta region. Results showed that industry and transportation are the major sources of O-3 and PM2.5 in the region, with industry contributing the most to the total mass of PM2.5. Additionally, during high pollution episodes, industry plays a larger role in PM2.5 pollution, while biogenic and open burning contributions are more important in high O-3 episodes.

Summary: Research shows that as Saharan dust travels from the Sahara Desert to Cape Verde and Puerto Rico, the proportion of Ca-bound P decreases, while the proportion of iron/aluminum-bound P increases. Laboratory experiments suggest that these changes may be attributed to increasing degrees of particle sorting and atmospheric acidification during dust transport.

Summary: A three-dimensional variant of the Potential Source Contribution Function (PSCF) model was used to identify source areas and altitudinal atmospheric layers associated with PM10 exceedances in Athens. The study revealed that direct Saharan dust intrusions from North Africa and regional combustion sources from the Balkans and Northern Greece were significant contributors to PM10 exceedances in different seasons. Additionally, winter PM10 exceedances were linked to northerly airflows and stagnant local emissions in Athens.

Summary: In recent years, the seasonal features of Asian dust storms have been altered by climate change and anthropogenic activities. This study focuses on the climatology of dust aerosols over the Jianghan Plain in central China. It shows that dust aerosols frequently intrude into the region in spring and winter, while occurrence frequencies decline in autumn and summer. The dust particles are mainly distributed at lower altitudes and are associated with the Taklimakan Desert and Gobi Desert. The study also finds a possible mix of local anthropogenic aerosols with dust particles.

Summary: The (AC)(3) project, established in 2016, collected a wealth of data on the physical, chemical, and meteorological properties of the Arctic atmosphere, cryosphere, and upper ocean. Short-term changes and long-term trends in Arctic climate parameters have been identified, such as increased atmospheric moistening, regional storm activities, winter warming in specific regions, and decreasing sea ice thickness and snow depth on sea ice. The project also made advancements in atmospheric-ocean and radiative transfer models, and discovered local marine/biogenic sources for cloud condensation nuclei and ice nucleating particles. Cross-cutting activities are being developed to further synthesize the results and answer key questions.

Summary: Equatorial waves play a significant role in tropical rainfall variability, but current numerical models struggle to accurately represent them. However, global simulations with higher resolutions are able to capture Kelvin, mixed-Rossby gravity, and equatorial Rossby waves consistently, regardless of model resolution and convective treatment. Explicit convection is necessary for smaller-scale inertio-gravity waves. Surprisingly, the associated rainfall signals do not correspond to wind patterns but are connected to mesoscale convective systems, highlighting the importance of jointly analyzing rainfall and dynamic aspects of equatorial waves.

Summary: Mineral dust particles with a wide range of diameters, from <0.1 μm to >100 μm, have unique interactions with various aspects of the Earth system. Coarse and supercoarse dust aerosols, defined as particles with diameters of 2.5-10 μm and 10-62.5 μm, have been found to be transported farther and more abundant than previously thought. These aerosols have significant impacts on dust-radiation interactions, dust-cloud interactions, atmospheric chemistry, and biogeochemistry. Recommendations have been made to improve the representation of coarse and supercoarse dust aerosols in models and remote sensing retrievals. Accurate representation of these aerosols is critical for understanding their impacts on the Earth system.

Summary: Aeolus is a satellite mission that provides global vertical profiles of horizontal line-of-sight winds, addressing the gap in the Global Observing System, particularly in the Tropics. This study investigates the impact of Aeolus data on weather analyses and forecasts by ECMWF and DWD, focusing on the West African Monsoon circulation during the summers of 2019 and 2020. Assimilating Aeolus data improves the prediction of zonal winds, especially for lead times above 24 hours. There are systematic differences in the representation of the African Easterly Jet North (AEJ-North) and Tropical Easterly Jet (TEJ) between the two analysis systems. The regions with the greatest influence of Aeolus data are the Intertropical Convergence Zone (ITCZ) for ECMWF and the upper troposphere for DWD.

Summary: Pyrocumulonimbus (pyroCb) are wildfire-generated convective clouds that can inject smoke directly into the stratosphere. In situ measurements of pyroCb smoke reveal its distinctive and exceptionally stable aerosol properties and define the long-term influence of pyroCb activity on the stratospheric aerosol budget. Analysis of 13 years of airborne observations shows that pyroCb are responsible for 10 to 25% of the black carbon and organic aerosols in the present-day lower stratosphere, with similar impacts in both the North and South Hemispheres. These results suggest that, should pyroCb increase in frequency and/or magnitude in future climates, they could generate dominant trends in stratospheric aerosol.

Summary: Air pollution is associated with increased risk of myocardial infarction. Factors such as socioeconomic status, comorbidities, financial stress, residential green space, or road traffic noise may modify this association. A study on over 1.9 million Danes aged 50-85 years showed that PM2.5 and other pollutants were associated with myocardial infarction. Lower education and income were associated with higher absolute risks, while comorbidities were consistently associated with higher risks.

Summary: Establishing the impacts of mineral dust on Earth's systems requires numerical models of the dust cycle, but there is often large model uncertainty due to unrealistic assumptions about dust emission frequency. Calibrating the models to match dust optical depth measurements may hide the true magnitude and frequency of dust emission events at the source. Therefore, it is essential to improve physically based dust emission modules.

Summary: Wildfires, especially extreme ones like the Australian wildfires in 2019-2020, release absorbing aerosols that have significant impacts on the atmosphere. The global climate impact of these wildfires is not only due to the emitted carbon dioxide but also the smoke aerosol released. This study uses simulations to show that the smoke from the Australian wildfires led to radiative forcing and subsequent adjustments in the stratosphere and troposphere, affecting temperature, humidity, cirrus amount, ice water path, and surface precipitation globally.

Summary: In this study, microphysical, optical, and environmental properties of contrail and natural cirrus were examined. It was found that pure contrail cirrus has higher ice particle concentration, smaller mass mean radius, and lower ice water content compared to the mixture of contrail, natural, and liquid-origin cirrus. The study also observed that contrail cirrus is more likely to occur in slightly ice-subsaturated air.
