How urban heterogeneity shapes near-surface wind fields
Ammonia emissions and crop yields in China to 2060 under SSP-RCP scenarios with climate change and nitrogen fertilization attribution
Climate change poses unprecedented challenges to agricultural sustainability, with profound implications for environmental quality and crop productivity. However, integrated assessments quantifying the specific contributions of climatic drivers versus management practices to agricultural ammonia (NH 3 ) emissions and crop yields remain limited in China, constraining precision air pollution control and threatening national food security. This stud…
Anthropogenic drivers of the accelerated decline in surface NO 2 over China during 2015–2022
China has experienced accelerated decline in surface NO 2 concentrations under the condition of steady reduction in NO x emissions over the past decade, but the reasons for such a nonlinear response in the changes of surface NO 2 to reduction in NO x emissions remain unexplored. Through integration of measurements, a chemical transport model (GEOS-Chem), and a random forest (RF) model, we comprehensively quantified the contributions of emissions,…
Mechanisms of high-temperature ozone suppression in Eastern China
Ozone (O 3 ) is a typical secondary photochemical pollutant, whose production typically increases under high temperature and radiation. However, emerging observational evidences reveal a notable alteration in the O 3 -temperature relationship under extremely heat conditions (referred to as O 3 suppression) in 20%–30% cities of China, yet the underlying mechanisms and driving forces remain unclear. This study provides a comprehensive investigation…
Intensifying heat extremes in China attributed to rising greenhouse gases and declining aerosols since the 2010s
Rising temperatures have increased the frequency, duration, and intensity of extreme temperature events over China in recent decades. The upward trends in heat extremes in China in the warm season (May–September) and their relationships with changes in aerosols and greenhouse gases are investigated using observations, reanalysis data and model results. Significant increasing trends in China are observed in daily maximum temperatures (TXx), heatwa…
Ammonia transfers through interprovincial agricultural trade and their health burden implications in China
The spatial mismatch between agricultural resources and market demand across China creates significant challenges for food security and environmental management. Although interprovincial agricultural trade can alleviate regional food supply pressures, substantial uncertainties persist regarding the associated ammonia (NH 3 ) emission transfers and their impacts on air quality and human health. Here we fill this gap using a linear programming mode…

The research delves into the intricate interaction between teacher support and student engagement, postulating that L2 grit and intended effort function as mediators within this dynamic. METHODS: We employed a cross-sectional design involving…
Long term variation of microphysical properties of black carbon in Beijing derived from observation and machine learning
The microphysical attributes of black carbon (BC) can determine its absorption and hygroscopic properties. However, long-term information is difficult to obtain from the field. In this study, the BC properties including mass concentration, the coating volume ratio (VR) relative to the refractory BC (rBC), the rBC diameter and the fraction of cloud condensation nuclei (CCN), are derived from a number of field experiments using a random forest mode…
Terrestrial moisture sources dominate summer precipitation fluctuations in Northwest China
Northwest China (NWC), is characterized by its arid and semi-arid environment, and exhibits high sensitivity to precipitation variations. Recent research indicates a wetting tendency over NWC, yet quantifying its moisture source remains challenging. Here, employing a 40 year simulation with Community Atmosphere Model version 5.1 (CAM5.1) coupled to an atmospheric water tracer algorithm, we ascertain that the dominant source of summer moisture ove…
Discordant future climate-driven changes in winter PM2.5 pollution across India under a warming climate
India’s megacities have been suffering from frequent winter particulate matter (PM2.5) pollution episodes, and how impacts of meteorology on air quality will evolve with time under a warming climate remains a concern. In this study, we identified conducive meteorological weather conditions in 5 megacities across India and found that quantile regression models can better describe the meteorological impacts under high pollution level and capture mo…
Status and Trends of Research on China’s Third Front Construction in English Language and Brief Comparison With Chinese Counterpart
Third Front construction was a massive defensive industrialization and economic campaign in response to the threat of war from both the Soviet Union and the United States in the 1960s in the remote and isolated hinterlands of China, which remained a top secret for many years before 1980s. Academic community has been making growing efforts in exploring its origin, history, development and influence ever since. As the largest industrial relocation …
Air pollution mitigation in North China through flexible heating policies
Central heating in North China produces severe air pollution, although the need for heating may be reduced by rising temperatures associated with climate change. The regional trend of mean heating length (HL) for North China was −0.32 d per year during 1961–2019. Compared with the 2010–2015 mean values, the start and end dates for central heating in the North China Plain (NCP) during 2050–2055 will delayed by 9 d and advanced by 12 d, respectivel…
DEnVar-based inversion system for ammonia emission estimation in China through assimilating Iasi ammonia retrievals
Atmospheric ammonia has been hazardous to the environment and human health for decades. Current inventories are usually constructed in a bottom-up manner and subject to uncertainties and incapable of reproducing the spatiotemporal characteristics of ammonia emission. Satellite measurements, for example, Infrared Atmospheric Sounder Interferometer (IASI) and Cross-Track Infrared Sounder, which provide global coverage of ammonia distribution, have …
Enso modulation of summertime tropospheric ozone over China
Ozone (O 3 ) is one of the most critical pollutants affecting air quality in China in recent years. In this study, different impacts of the El Niño–Southern Oscillation (ENSO) warm/cold phases on summertime tropospheric O 3 over China are examined based on model simulations, ground measurements, and reanalysis data. Summertime surface O 3 concentrations in China show a positive correlation with ENSO index during years 1990–2019, with the largest …
Mitigating ozone damage to ecosystem productivity through sectoral and regional emission controls
The land ecosystems of China are estimated to provide an important sink for the increased atmospheric carbon dioxide (CO 2 ), but are undermined by severe ozone (O 3 ) pollution. Mitigation of O 3 damage to ecosystems remains a challenge considering that O 3 precursors are emitted from a wide range of anthropogenic sectors and O 3 formations are also affected by regional transport. Here, we combine chemical transport and dynamic vegetation models…
A humidity-based exposure index representing ozone damage effects on vegetation
Surface ozone (O 3 ) is detrimental to plant health. Traditional exposure indexes, such as accumulated hourly O 3 concentrations over a threshold of 40 ppb (AOT40), are easy to be derived and widely used to assess O 3 damage effects on vegetation. However, the regulation of environmental stresses on O 3 stomatal uptake is ignored. In comparison, the dose-based indexes are much more reasonable but require complex parameterization that hinders furt…
Is the efficacy of satellite-based inversion of SO 2 emission model dependent
Satellite-based inverse modeling has the potential to drive aerosol precursor emissions, but its efficacy for improving chemistry transport models (CTMs) remains elusive because of its likely inherent dependence on the error characteristics of a specific CTM used for the inversion. This issue is quantitively assessed here by using three CTMs. We show that SO 2 emissions from global GEOS-Chem adjoint model and OMI SO 2 data, when combined with spa…
Anthropogenic drivers of 2013–2017 trends in summer surface ozone in China
Significance Drastic air pollution control in China since 2013 has achieved sharp decreases in fine particulate matter (PM 2.5 ), but ozone pollution has not improved. After removing the effect of meteorological variability, we find that surface ozone has increased in megacity clusters of China, notably Beijing and Shanghai. The increasing trend cannot be simply explained by changes in anthropogenic precursor [NO x and volatile organic compound (…
Influence of Industrialization and Environmental Protection on Environmental Pollution
In order to quantitatively study the effect of environmental protection in China since the twenty-first century and the environmental pollution projected for the next ten years (under the model of extensive economic development), this paper establishes a Bayesian regulation back propagation neural network (BRBPNN) to analyze the typical pollutants (i.e., cadmium (Cd) and benzopyrene (BaP)) for Taihu Lake, a typical Chinese freshwater lake. For th…
Analysis of Historical Sources of Heavy Metals in Lake Taihu Based on the Positive Matrix Factorization Model
Analysis of sediment grain sizes and heavy metal correlations in the western part of Lake Taihu shows that the grain size of the sediment is stable as a whole. With increasing depth, the grain size tends to decrease. Heavy metals such as Cr, Cd, Pd and Sr are strongly correlated and influence each other. Based on the positive matrix factorization (PMF) model, this study classified the origin of heavy metals in the sediments of western Lake Taihu …
