Summary: Most global aerosol models approximate dust as spherical particles, whereas most remote sensing retrieval algorithms approximate dust as spheroidal particles with a shape distribution that conflicts with measurements. These inconsistent and inaccurate shape assumptions generate biases in dust single-scattering properties. This study uses observationally constrained shape distributions to approximate dust as triaxial ellipsoidal particles and obtains dust single-scattering properties.

Summary: This study investigated the scavenging of anthropogenic aerosols by mineral dust in a polluted environment, based on comprehensive observations of a long durative dust event in north China from March 15 to 18, 2021. The combined observations of a Raman-depolarization lidar (355 nm) and a micro-pulse lidar (532 nm) showed that dust particles become more spherical after mixing with anthropogenic pollutants, likely due to mixing with anthropogenic aerosols. The decrease in anthropogenic aerosol in PM2.5 during the dust event, especially for inorganic components such as nitrate, sulfate, and ammonium, supports this viewpoint. The mass concentration of anthropogenic aerosol in PM2.5 decreased by 78% in the later period of the dust event. Further analysis indicated that this decrease is caused by the coating of fine anthropogenic aerosols on coarse dust particles, enhancing the scavenging of anthropogenic aerosols.

Summary: Dust aerosols in the atmosphere are efficient ice nucleating particles in temperatures below -15 degrees C. This study finds that dust particles with feldspar and quartz are the most active ice nuclei. By comparing model predictions with observations, it is found that the mineralogy of dust clouds has a significant impact on ice nucleating particle concentration, with mineralogy-sensitive and mineralogy-indifferent parameterizations yielding different results.

Summary: The evolution and properties of a Saharan dust plume near Karlsruhe, Germany were studied using scanning LiDAR, a vertically pointing LiDAR, a sun photometer, and the transport model ICON-ART. The study discussed the advantages of scanning aerosol LiDAR and validated a method to determine LiDAR ratios independently. The measurements showed good agreement with previous studies and the transport model accurately predicted the plume's arrival time and structure. The work will be useful for future studies characterizing aerosol particles with scanning LiDARs.

Summary: The study on volcanic ash monitoring around Sakurajima volcano in Kagoshima, Japan showed a correlation between extinction coefficients and volcanic activity, but not an absolute correspondence. Changes in wind direction may lead to peaks in extinction coefficients, which do not necessarily coincide with peaks in ash fall density, possibly due to differences in particle size.

Summary: Coincident profiles from space-borne and ground-based lidar provide a unique opportunity to estimate planetary boundary layer height. Differences between PBLH derived from CALIOP and SNU lidar are influenced by signal-to-noise ratio and aerosol optical depth, with CALIOP typically showing higher PBLH. Improved agreement is seen after eliminating multilayer cases, indicating reliable PBL detection using CALIOP for daytime. Further investigations are needed for nighttime PBLHs to better understand differences in frequency distribution compared to sounding data.

Summary: This study investigated the contribution of weak Asian dust particles to PM2.5 concentration during a high PM2.5 episode in Seoul, Korea. It was found that Asian dust particles transported concurrently with anthropogenic pollution aerosols contributed to elevated PM2.5 concentration. Unlike severe Asian dust episodes, most air quality forecasting models struggle to accurately predict and alert the relatively low Asian dust particle concentrations during high PM2.5 haze episodes in winter-spring.

Summary: Ensemble future climate projections using the MRI-ESM2.0 model showed that sand and dust storm (SDS) emissions in the Gobi Desert are projected to increase in spring and autumn with warmer climate scenarios, due to changes in friction velocity and erodibility. The model also reproduced the decreasing trend of SDS emissions in the early 21st century. Friction velocity and ground temperature were found to be highly correlated with SDS emissions.

Summary: This study compares three aerosol representation methods in the NHM-Chem model: five-category non-equilibrium, three-category non-equilibrium, and bulk equilibrium methods. The study found that the CPU times of the five-category and three-category methods were 91% and 44% greater than that of the bulk method, respectively. The bulk equilibrium method is suitable for operational forecasting, while the simulated results of the five-category and three-category methods were not significantly different in terms of surface concentrations and depositions of bulk chemical species. However, the internal mixture assumption in the three-category method led to significant differences in particle size distribution and hygroscopicity.

Summary: The size and morphology of nanoparticles significantly impact their performance. Current methods, such as electron microscopy or atomic force microscopy, have limitations in sample preparation, processing time, and quantitative characterization. Therefore, it is crucial to develop a fast, accurate, and statistical method for measuring nanoparticle size and morphology. In this study, a new method called polarized imaging dynamic light scattering (PIDLS) is proposed, which irradiates nanoparticles with a vertical linearly polarized laser beam and utilizes a polarization camera to collect dynamic light scattering images at different polarization directions. The method effectively determines particle size, morphology, and sphericity based on depolarization patterns and degree of linear polarization. PIDLS also enables simultaneous measurement of particle size and morphology distributions, allowing for the evaluation of particle uniformity. The effectiveness of PIDLS is validated with the measurement of five types of industrial titanium dioxide.

Summary: By modeling neighboring particles as a single coarse-grained particle, the discrete particle method (DPM) can now simulate industrial-scale particle-fluid systems. However, there is still a lack of a systematic approach to determine the properties and interaction models of these coarse-grained particles, which affects the predictability of the method. In this study, kernel functions for modeling the coarse-grained particles are constructed based on the analysis of collisions between predefined particle groups, and the model parameters are determined by equating the statistical properties of the coarse-grained particles to those of the real particles. This approach has been effective in simulating the homogeneous cooling of granular gas and experimental fluidized beds.

Summary: The particle size distribution (PSD) curve is an important expression of soil properties. However, existing characteristic parameters can only represent some points of the curve and fail to capture all the information. This paper introduces a new fraction characteristic parameter based on grading entropy and proposes a refined presentation method for the PSD curve. The new method not only represents the differences in curve width more accurately but also has higher discrimination ability. The application of this method in describing deposit distribution and predicting soil hydraulic conductivity is discussed. The research results can provide reference for the refined representation of PSD curves.

Summary: Reasonable reactor design is crucial for increasing the C2 yield in the oxidative coupling of methane (OCM). This study focused on large-scale fluidized bed reactors and conducted experiments and simulations to investigate their hydrodynamics and reaction performance. The results showed that the consecutive reactions of ethylene were severe in the bubbling fluidized bed (BFB) reactor due to gas back-mixing, high solids holdup, and non-uniform solids distribution, while they were negligible in the riser reactor. Both reactors achieved isothermal operation for the OCM process, with the riser reactor showing higher C2 selectivity and yield compared to the BFB reactor. This study provides valuable information for OCM reactor design and commercialization.
