This study analyzes summertime ozone trends in East and Southeast Asia derived from a comprehensive observational database spanning from 1995 to 2019, incorporating aircraft observations, ozonesonde data, and measurements from 2500 surface sites. Multiple models are applied to attribute to changes in anthropogenic emissions and climate. The results highlight that increases in anthropogenic emissions are the primary driver of ozone increases both in the free troposphere and at the surface.

Understanding aerosol size distribution helps us predict how aerosols move, grow, and interact with the environment and climate. We used "maximum entropy" to demonstrate that the aerosol particle number size distribution would follow the Weibull distribution in the clean atmosphere during the new particle formation and growth process. The observations showed good consistency with the theoretical analysis.

During the 2022 Beijing Winter Olympics, we conducted field observations of N2O5. By comparing pre- and post-Olympic pollutant levels, we evaluated the impact of emission reductions on nocturnal chemistry. The results showed that the reactivity of nitric oxide (NO) and volatile organic compounds (VOCs) with NO3 decreased, and that the heterogeneous uptake of N2O5 played a critical role in nocturnal nitrate formation.

We present observational evidence for widespread SI influence on surface ozone pollution from western plateaus to eastern plains over China in a deep trough event based on multi-site ozonesondes, nationwide surface ozone measurements, and fully-validate atmospheric ozone reanalsyis. The observational results refine the fundamental understanding of stratospheric ozone intrusion and its contribution to surface ozone pollution in China.

We observed a strong increase in deseasonalized ozone at urban stations on the Tibetan Plateau from 2015 to 2019, far exceeding the trend at the baseline station Waliguan and the Tibet Plateau average trend of four tropospheric ozone products. By combining multiple datasets and modeling approaches, we identified the main contributing factors as more frequent transport passing through the lower layers of high-emission regions and the rapid increase in anthropogenic nitrogen oxide emissions.

Ozone (O3) deposition is a key process that removes surface O3, affecting air quality, ecosystems and climate change. We conducted O3 deposition measurement over a wheat canopy using a newly relaxed eddy accumulation flux system. Large variabilities in O3 deposition were detected, mainly determined by crop growth and modulated by various environmental factors. More O3 deposition observations over different surfaces are needed for exploring deposition mechanisms and model optimization.

Our study examined the long-term trends of atmospheric ammonia in urban Beijing from 2009 to 2020. We found that the trends did not match satellite data or emission estimates, revealing complexities in ammonia sources. While seasonal variations in ammonia were temperature-dependent, daily variations were correlated with water vapor. We also found an increasing contribution of ammonia reduction, emphasizing its importance in mitigating the effects of fine particulate matter in Beijing.

Chen et al. (2022) attributed the nocturnal ozone enhancement (NOE) during the night of 31 July 2021 in the North China Plain (NCP) to "the direct stratospheric intrusion to reach the surface". We analyzed in situ data from the NCP. Our results do not suggest that there was a significant impact from the stratosphere on surface ozone during the NOE. We argue that the NOE was not caused by stratospheric intrusion but originated from fresh photochemical production in the lower troposphere.

@Tibet field campaigns 2021 discovered surprisingly high levels and activity contributions of oxygenated volatile organic compounds on the southeast of the Tibetan Plateau, which suggests that OVOCs may play a larger role in the chemical reactions that occur in high-altitude regions than previously thought.

The atmospheric pollution and formation mechanisms of particulate-bound alkyl nitrate in Beijing were studied. C9–C16 long-chain n-alkyl nitrates negatively correlated with O3 but positively correlated with PM2.5 and NO2, so they may not be produced during gas-phase homogeneous reactions in the photochemical process but form through reactions between alkanes and nitrates on PM surfaces. Particulate-bound n-alkyl nitrates strongly affect both haze pollution and atmospheric visibility.

Online volatile organic compound (VOC) measurements by gas chromatography–mass spectrometry, with other O3 precursors, were used to identify key VOC and other key sources in Lhasa. Total VOCs (TVOCs), alkanes, and aromatics are half as abundant as in Beijing. Oxygenated VOCs (OVOCs) consist of 52 % of the TVOCs. Alkenes and OVOCs account for 80 % of the ozone formation potential. Aromatics dominate secondary organic aerosol potential. Positive matrix factorization decomposed residential sources.

We reported an optimized system (Mea-OPR) for direct measurement of ozone production rate, which showed a precise, sensitive and reliable measurement of OPR for at least urban and suburban atmosphere, and active O3 photochemical production in winter Beijing. Herein, the Mea-OPR system also shows its potential in exploring the fundamental O3 photochemistry, i.e., surprisingly high ozone production even under high-NOx conditions.

Tropospheric ozone (O3) and peroxyacetyl nitrate (PAN) are both photochemical pollutants harmful to the ecological environment and human health, especially in the Tibetan Plateau (TP). However, the factors determining their variations in the TP have not been comprehensively investigated. Results from field measurements and observation-based models revealed that day-to-day variations in O3 and PAN were in fact controlled by distinct physiochemical processes.

The characteristics of n-alkanes and the contributions of various sources of PM2.5 in the atmosphere in Beijing were studied. There were marked seasonal and diurnal differences in the n-alkane concentrations (p<0.01). Particulate-bound n-alkanes were supplied by anthropogenic and biogenic sources; fossil fuel combustion was the dominant contributor. Vehicle exhausts strongly affect PM2.5 pollution. Controlling vehicle exhaust emissions is key to control n-alkane and PM2.5 pollution in Beijing.

The Tibetan Plateau (TP), the highest plateau in the world, plays a crucial role in regional and global climate. To examine the fingerprint left by human activities on the originally remote atmosphere, size distributions of particles from the ground to about 800 m were measured for the first time in summer 2020 in Lhasa, one of a few urbanized cities on TP. Potential sources of particles at different heights were explored. The contribution of emissions from religious activities was highlighted.

China has been experiencing rapid changes in emissions of air pollutants in recent decades. NOx and SO2 measurements from 2006 to 2016 at the Lin’an World Meteorological Organization Global Atmospheric Watch station were used to characterize the seasonal and diurnal variations and study the long-term trends. This study reaffirms China’s success in controlling both NOx and SO2 in the Yangtze River Delta but indicates at the same time a necessity to strengthen the NOx emission control.

Photochemical pollution over the North China Plain (NCP) is attracting much concern. Our observations at a rural site in the NCP identified high peroxyacetyl nitrate (PAN) concentrations, even on cold days. Increased acetaldehyde concentration and hydroxyl radical production rates drive fast PAN formation. Moreover, our study emphasizes the importance of formaldehyde photolysis in PAN formation and calls for implementing strict volatile organic compound controls after summer over the NCP.

Haze related to particulate matter has become a big problem in eastern China, and ammonia (NH3) plays an important role in secondary particulate matter formation. In this work, variations in the NH3 mixing ratio showed that the contributions of NH3 sources and sinks in urban and suburban areas were quite different, although the areas were under the influence of similar weather systems. This study furthers the understanding of the behavior of NH3 in a megacity environment.

Field observations found that released NOx on the glacier surface of the Tibetan Plateau, an important snow-covered region in the northern mid-latitudes, had a higher concentration than in Antarctic and Arctic regions. Such evidence, and such high fluxes as observed here on the Tibetan plateau is novel. That such high concentrations of nitrogen oxides can be found in remote areas is interesting and important for the oxidative budget of the boundary layer.

CO is one of the major air pollutants. Our study showed that the long-term CO levels at a background station in one of the most developed areas of China decreased significantly and verified that this downward trend was attributed to the decrease in anthropogenic emissions, which indicated that the adopted pollution control policies were effective. Also, this decrease has an implication for the atmospheric chemistry considering the negative correlation between CO levels and OH radical's lifetime.

We study O3 retrievals in the 3040 cm-1 spectral range from FTIR measurements at Xianghe China (39.75° N, 116.96° E; 50 m a.s.l.) between June 2018 and December 2019. It was found that the FTIR O3 (3040 cm-1) retrievals capture the seasonal and synoptic variations of O3 very well. The systematic and random uncertainties of FTIR O3 (3040 cm-1) total column are about 13.6 % and 1.4 %, respectively. The DOFS is 2.4±0.3 (1σ), with two individual pieces of information in surface–20 km and 20–40 km.

Short summary
Significant decreases in annual mean NOx from 2011 to 2016 and SO2 from 2008 to 2016 confirm the effectiveness of relevant control measures on the reduction in NOx and SO2 emissions in the North China Plain (NCP). NOx at SDZ had a weaker influence than SO2 on the emission reduction in Beijing and other areas in the NCP. An increase in the number of motor vehicles and weak traffic restrictions have caused vehicle emissions of NOx, which indicates that NOx emission control should be strengthened.
Significant decreases in annual mean NOx from 2011 to 2016 and SO2 from 2008 to 2016 confirm the...
