Summary: The study shows that in the tropical and subtropical Indian Ocean region, organic aerosols are mainly derived from the ocean, especially during the wet season. In contrast, during the dry season, they are mainly influenced by volcanic eruptions. Marine secondary organic aerosols predominantly contribute to the observed WSOC mass in the wet season.

Summary: Typical dispersion simulations use mesoscale models with grid spacing greater than 1 km, while advances in computing power have allowed for the use of Large Eddy Simulations (LES) with grid spacing less than 100 m. In this study, the WRF mesoscale/LES model and the HYSPLIT particle dispersion model were used to simulate SF6 transport, using a grayscale-aware scheme with different nest sizes. The results showed that the WRF/LES simulation was in agreement with meteorological observations, but the HYSPLIT SF6 simulations had insufficient subgrid turbulence kinetic energy, leading to over predictions of surface SF6 concentration and insufficient vertical transport. The best agreement with observations was obtained by combining the WRF/LES large-scale and subgrid turbulence with a HYSPLIT parameterized turbulence profile.

Summary: This study analyzed the moisture sources of two major extreme precipitation events in summer in the Iberian Peninsula. One event was associated with moisture from the central and eastern North Atlantic, while the other event was mainly influenced by moisture from the western Mediterranean Sea. Understanding the moisture sources of extreme precipitation events is important for their prediction and impact assessment.

Summary: Tropospheric ozone pollution has become prominent in the North China Plain in China over the past decade. Through measurements and simulations in Luoyang City in 2019, it was found that industrial and traffic emissions were the main sources of VOC pollution in urban areas, and O-3 formation was collectively controlled by VOCs and NOx. The study supports the effectiveness of simultaneous controls of NOx and VOCs in reducing tropospheric O-3 and suggests that joint regional control policies have the potential to address O-3 pollution in China.

Summary: The selection of power plant sites, especially nuclear power plants, involves considerations of radiation doses and dispersion of radioactive particles. In this study, a combination of weather forecasting and particle dispersion codes were used to simulate an accidental release from a nuclear power plant, showing better accuracy than previous investigations. The study found that WRF predictions of wind speeds and directions had a significant impact on tracking particle trajectories and spatial dose distribution.

Summary: During the COVID-19 lockdown, the reduction in human activities provided a valuable opportunity to study the impact of meteorological conditions and human activities on air quality. This study comprehensively considered large-scale weather circulation, local meteorological conditions, and the impact of human activities in the northeast region of China. The concentration of major air pollutants was systematically studied, and it was found that pollutants such as PM2.5, NO2, CO, and SO2 are more susceptible to human activities and local meteorological conditions, while changes in O-3 concentration are more closely related to changes in weather circulation types.

Summary: This study investigated the interaction between heat waves and urban heat island effects in a tropical city by studying the heat wave event in Singapore in April 2016. The results showed that there was no significant amplification of urban heat island intensity during the heat wave period, indicating the absence of a synergistic effect between heat waves and urban heat island effects in the tropical city. This suggests that the interaction between heat waves and urban heat island effects may differ in tropical cities compared to cities in temperate climate zones.

Data from balloon-borne instruments were used to characterize the cirrus and its environment. Optical modeling was employed to estimate the cirrus microphysical properties, indicating that the formation may have been triggered by a high-frequency gravity wave.

Summary: This article presents the results of the AEROMARINE field campaign conducted between February and April 2019 off the coast of Reunion Island in the Southern Indian Ocean. The study analyzed marine aerosols, their distribution, and variability, comparing measurements from aircraft flights and ground-based instruments with long-term data from existing stations. The findings suggest that aerosols above 1.5 km are mainly from regional sources, with little impact from the local environment, and that daytime marine aerosol distributions in the free troposphere are representative of nighttime measurements at high altitudes.

Summary: Mercury (Hg) stable isotopes were used to investigate the sources and deposition of atmospheric Hg. The study found that atmospheric Hg deposition and plant Hg uptake covaried with dust deposition and were influenced by humidity. The Hg isotope signatures in modern AMS gaseous Hg-0 and rainfall were similar to those in the Northern Hemisphere. The study also suggested that peat Hg isotope records might be a valid rainfall indicator.

Summary: Iodine is an active trace element in atmospheric chemistry that can destroy ozone and form particles. Its emissions have increased threefold since 1950 and are expected to continue rising. In laboratory experiments, iodooxy hypoiodite (IOIO) was shown to efficiently convert into iodic acid (HIO3) via reactions IOIO + O-3 -> IOIO4 and IOIO4 + H2O -> HIO3 + HOI + O-(1)(2). This laboratory-derived mechanism explains field observations of daytime HIO3 in the remote lower free troposphere and suggests a catalytic role of iodine in aerosol formation.

The model is able to efficiently reproduce the macro features of clouds, such as cloud occurrences, cloud water content magnitudes, and cloud-rain links, based on comparisons with in situ measurements and observations. It can be adjusted to different spatiotemporal resolutions and used in various regions as long as implementation data is available.

Summary: Reliably recording low GEM concentrations in remote regions is challenging. In this study, passive air samplers were deployed in extreme environments for up to three years. The size of the sequestered mercury and contamination of field blank samples influenced the reliable recording of GEM concentrations. Longer deployment periods and storage in sealed glass jars were found to be effective in reducing contamination. However, sampling in Antarctica was compromised due to extreme temperatures and material failure.

Summary: This study comprehensively investigates the atmospheric concentrations of CO2, CH4, and CO in Reunion Island using observations and simulations from the WRF-GHG model. The model shows good performance in reproducing meteorological measurements, especially temperature. However, it underestimates the nocturnal buildup of CO2 and fails to accurately reproduce CH4 observations due to seasonal biases and overestimated anthropogenic fluxes. The observations at the high-altitude Maldo Observatory can capture both anthropogenic signals and biomass burning enhancements. High model resolution is needed to accurately represent surface observations, especially in areas with complex topography and local wind patterns. A model resolution of 50km might be sufficient to simulate column FTIR observations.

The results showed a decrease in NO2 concentrations, especially in urban and high-traffic areas. However, socially vulnerable populations still experienced higher levels of NO2 exposure. The study suggests that reducing NO2 disparities, particularly racial inequity, can be achieved through continued regulatory actions targeting traffic-related NOx emissions.

Summary: This study investigates the chemical composition and oxidative potential of PM10 particles in the Po Valley, Italy, and demonstrates the impact of high levels of atmosphere ammonia. The rural area had significantly higher ammonia concentrations compared to the urban site, resulting in higher levels of secondary inorganic aerosol. Although the SIA components did not contribute significantly to the PM10 oxidative reactivity, they were correlated with the oxidative potential measurements. This suggests that the contribution of SIA to PM oxidative toxicity cannot be ignored.
