Summary: The field observation study of total suspended particles (TSPs) in the Tianshan Glaciological Station reveals seasonal variations in the concentrations, with higher levels in autumn and lower levels in winter. The impact of stationary sources emissions outweighs that of mobile sources. The concentration of secondary organic carbon (SOC) is higher in summer and autumn, indicating frequent secondary formation of organic aerosols in summer. Fossil fuel combustion sources have a significant impact on the glaciers, with diagnostic mass ratios confirming this. Factors such as rock salt, dust, coal combustion, and automobile exhaust contribute to the composition of aerosols.

Summary: Lockdown measures in response to the COVID-19 outbreak led to a reduction in anthropogenic emissions in Beijing. However, unfavorable meteorological conditions and inappropriate precursor reduction ratios caused an increase in PM2.5 concentrations and a significant increase in O-3 concentrations. Cluster analysis revealed that short-range transport played a significant role in local PM2.5 accumulation, while long-range northwest airflows contributed more to O-3 accumulation, weakening with changing seasons. Potential source areas of PM2.5 were mainly located in central and southern Hebei and southwestern Shandong, while O-3 source areas were centered in the Beijing-Tianjin-Hebei region and Shandong province.

Summary: In this study, the formation, characteristics, and sources of high O3 concentrations at the Wutaishan station were investigated using a novel approach based on the mixing layer depth of a backwards trajectory. The results show that the diurnal variation in O3 concentration differs between warm and cold seasons, and the transport process significantly influences the high O3 concentrations at the station. The residence time of airflow in the mixing layer is closely related to the O3 concentration, and the effect of free tropospheric airflows on increasing O3 concentrations is apparent during cold seasons.

Summary: This study quantified the contributions of moisture source regions to precipitation in the Great Lakes Region (GLR) and identified the primary sources of moisture as the Great Plains (GPs) and the GLR itself. The findings showed a shift in the peak timing of moisture contribution from the GLR and GPs, explaining the double peaks in GLR precipitation in June and September. Furthermore, it was observed that moisture from the GPs contributed more to heavy precipitation, while moisture from the GLR contributed more to light precipitation. Additionally, there was a statistically significant increasing trend in moisture contribution from the mid-Pacific, attributed to changes in atmospheric circulation.

Summary: The iron and steel industry is significant for socio-economic progress but also contributes to greenhouse gas emissions and air pollution. This study provides a comprehensive analysis of global emissions from the industry over the past 60 years and predicts future trends up to 2050. The findings highlight the different trends for various pollutants, such as a consistent decrease in PM2.5 emissions from 1970 to 2000 and recent declines in NOx and SO2 emissions due to stricter controls. Projections suggest that developing nations (excluding China) will contribute a larger share of global PM2.5 emissions by 2050.

Summary: In early 2020, two unique events - the decline of ship activities due to COVID-19 and the global enforcement of low-sulfur fuel oil for ships - perturbed ship emissions of pollutants around Southern China, providing insights into their impacts on regional air quality. The decline in ship emissions led to decreases in NOx, SO2, and primary PM2.5 over Southern China, with the most significant reductions occurring in coastal waters and inland waterways for NOx and outside the Chinese Domestic Emission Control Area for SO2 and primary PM2.5. Despite the decrease in surface NO2 levels, there was an increase in surface ozone levels. Ship emissions were found to contribute significantly to surface NO2 concentrations over Guangdong in winter. Therefore, future abatements of ship emissions should be implemented synergistically with reductions of land-borne anthropogenic emissions to effectively alleviate regional ozone pollution.

Summary: This study investigates the impact of multiple ozone observations from GEMS geostationary satellite, LEO satellite, and surface networks on summertime ozone simulations through data assimilation. The results show that data assimilation improves the monitoring of surface ozone exceedance, spatial patterns, and diurnal variations, and reduces regional mean negative bias and root-mean-square error (RMSE). The joint assimilation of GEMS and surface observations performs the best, but GEMS may mask the added value of LEO measurements, which are crucial for constraining surface and upper tropospheric ozone simulations when observations from other platforms are not sufficient.
