Summary: This study presents a diagnostic analysis of the interannual variation of regional climate and its impact on biomass burning aerosol emissions in peninsular Southeast Asia (PSEA). It identifies four climatic factors governing the emission and transport of PSEA biomass burning aerosols and reveals a significant correlation with the El Nin similar to o-Southern Oscillation (ENSO). The results contribute to a better understanding and improved model simulations of aerosol-climate interactions in South and Southeast Asian monsoon regions.

Summary: This study proposes a multi-objective optimization model to determine optimal retrofitting strategies to enhance community resilience under multiple hazards. The model is applied to analyze the impact of earthquake and tsunami hazards on the community of Seaside, Oregon. The results show that retrofitting buildings to achieve higher seismic codes can significantly reduce the impact of natural hazards on structural damage, population dislocation, and building repair times. It highlights the importance of considering geographical location and mitigation measures when optimizing retrofitting strategies.

Summary: In this study, the laser-induced fluorescence technique was used to observe scattered and fluorescent signals from fluorescent polystyrene latex particles. The ratio of fluorescence to scattered signal intensities was found to be almost equal for particles of the same size, allowing for the separate observation of mixed-size fluorescent particles. Relative fluorescence intensities were obtained by incorporating ratios of fluorescence to scattered signal and relative scattered signal intensities.

Summary: Phonation has been found to be a potent transmission route for the COVID-19 virus. To control transmission, it is important to measure the amount of aerosols produced by speech. Researchers used digital in-line holography to overcome experimental challenges and successfully imaged the formation and deformation of saliva filaments in the mouth during speech, as well as the resulting aerosolized droplets.

Summary: Surface ozone, a major air pollutant, is influenced by stratosphere-troposphere exchange (STE) which contributes to both the decrease and increase of surface ozone in the Southern and Northern Hemispheres, respectively. Additionally, global warming is expected to worsen surface ozone pollution in the future.

Summary: Segregated bimetallic nanoparticles, such as core-shell nanoparticles, have attracted widespread interest in various fields like biomedicine, catalysis, and optoelectronics. Aerosol technology provides an optimal platform for controlling the size, structure, and composition of nanoparticles, which are crucial parameters for tuning the material performance for specific applications. In this study, researchers developed a novel evaporator design that allows on-line coating of core particles with a shell directly in the gas phase. By utilizing a local heater, the researchers were able to decouple the heating process of the evaporating material from the aerosol particles, thereby limiting core-shell alloying. The resulting core-shell particle formation with controllable shell thickness was demonstrated using evaporation of zinc onto core particles of gold, tin, and bismuth. Simple models were also discussed to explain the observed growth process inside the evaporator and the formation of the shell.

Summary: In this paper, a hybrid gain data assimilation method was introduced into the GRAPES_Meso model, and combined with the multiscale incremental analysis update method to improve its forecasting performance. The results showed that the HGDA scheme outperformed the GRAPES-3DVAR scheme in forecasting the tropical cyclone position, intensity, and precipitation. The HGDA multiscale IAU scheme achieved the best performance, with higher threat scores and equitable threat scores compared to the 3DVAR multiscale IAU method.

Summary: Reliable precipitation information is crucial for scientific and operational applications. Open-access gridded precipitation products (OGPPs) are important sources due to their continuous spatiotemporal coverage. This study proposes a methodology to comprehensively compare the accuracies and stabilities of ten different OGPPs, particularly in mountainous basins. The results show high accuracy but unstable performance of all OGPPs, with multi-source fusion-type products offering better stability and accuracy. Multi-source weighted-ensemble precipitation and climate prediction center morphing method products exhibit the best comprehensive performance.

Summary: Overall, emergency management plans for extreme heat events in the U.S. show some level of consistency, but there are significant variations in response thresholds and metrics across different locations. Some cities have started adapting response thresholds based on local epidemiological studies, but there are still areas that have not lowered thresholds during cascading hazard events.

Summary: Significant phase shifts in winter surface air temperature (SAT) anomalies have occurred in East Asia in recent years, leading to detrimental effects on socio-economic activities. In this study, the fourth principal mode of month-to-month SAT variations over EA in winter was identified, representing subseasonal SAT reversals over the mid-high latitudes of EA during late winter. The formation of this mode is accompanied by stratospheric temperature anomalies over eastern Siberia-Alaska in January.

Summary: This study systematically evaluated the AOD products of the DB and MAIAC algorithms based on MODIS over bright surfaces, and investigated the underestimation of AOD affected by various factors. The results indicated that the MAIAC products performed better than DB, and the C6.1 MAIAC showed slight improvement compared to C6.

Summary: This study analyzes the wildfire hazard in a 115,000 ha landscape in Portugal and explores the threat posed to assets of pulp paper companies. It finds that eucalypt plantations not managed by the companies, particularly those with ages between 6 and 9 years, present a major risk. Over half of the landscape has the potential for large wildfires.

Summary: This study compares the atmospheric environment before rainfall and before storms using sounding measurements and ERA5 reanalysis data. The results show that ERA5 reanalysis data cannot accurately capture the convective environment before rainfall in most cases, especially in western China. Therefore, the findings highlight the need to integrate reanalysis with sounding measurements to better characterize the pre-rainfall and pre-storm environment.

Summary: This study investigated the contamination, eco-health hazards, and influencing factors of certain carcinogenic toxic elements in resuspendable surface dust in urban communities in Xi'an. The results showed that these elements posed a high cancer risk, particularly to children. Traffic and residential activities were identified as important factors influencing the pollution and risk, while vegetation distribution in the city was found to reduce the risk.
