Frequent extreme air pollution episodes in China accompanied with high concentrations of particulate matters (PM2.5) and ozone (O3) are partly supported by meteorological conditions. However, the relationships between variables extremes can be poorly estimated solely based on mean pollutant level. In this study, we use quantile regression to investigate sensitivities PM2.5 O3 extremes, benefiting from nationwide observations pollutants over 2013–2019 China. Results show that surface winds...
Heat waves and air pollution extremes exert compounding effects on human health food security may worsen under future climate change. On the basis of reconstructed daily O3 levels in China meteorological reanalysis, we found that interannual variability frequency summertime co-occurrence heat wave is regulated mainly by a combination springtime warming western Pacific Ocean, Indian Ross Sea. These sea surface temperature anomalies impose influences precipitation, radiation, etc., to modulate...
Data-driven medium-range weather forecasting has attracted much attention in recent years. However, the accuracy at high resolution is unsatisfactory currently. Pursuing high-resolution and high-quality forecasting, we develop a data-driven model SwinRDM which integrates an improved version of SwinRNN with diffusion model. performs predictions 0.25-degree achieves superior to IFS (Integrated Forecast System), state-of-the-art operational NWP model, on representative atmospheric variables...
Ecological and environmental protection is a key issue that cannot be ignored in the process of urbanization. To achieve goal urban sustainable development, dynamic complex relationship between urbanization ecological environment must coordinated. A comprehensive evaluation 16 cities within Chengdu-Chongqing agglomeration from 2011 to 2020 utilized entropy weight method, super-SBM model, coupling coordination degree model analyze levels, efficiency, their interplay. The findings reveal...
Brown carbon (BrC) has been recognized as an important light-absorbing carbonaceous aerosol, yet understanding of its influence on regional climate and air quality lacking, mainly due to the ignorance coupled meteorology-chemistry models. Besides, assumptions about emissions in previous explorations might cause large uncertainties estimates. Here, we implemented a BrC module into WRF-Chem model that considers source-dependent absorption avoids caused by emission intensities. To our best...
The estrogenic activity of dieldrin, toxaphene, and an equimolar mixture both compounds (dieldrin/toxaphene) was investigated in the 21-day-old B6C3F1 mouse uterus, MCF-7 human breast cancer cells, yeast-based reporter gene assays. Treatment animals with 17beta-estradiol (E2) (0.0053 kg/day x3) resulted a 3.1-, 4.8-, 7.8-fold increase uterine wet weight, peroxidase activity, progesterone receptor binding, respectively. In contrast, treatment 2.5, 15 60 micromol/kg (x3) doses or...
To investigate the association between particulate matter and incidence, disability, mortality of stroke, we reported burden stroke attributable to (PM
Inflammatory lung diseases are characterized by chronic inflammation and oxidant/antioxidant imbalance. Exposure to some kinds of volatile organic compounds (VOCs) leads inflammation, oxidative stress, immune modulation. However, it is suspected that sub‐chronic exposure low‐dose VOCs mixture induces or aggravates inflammation. To clarify the effect this on inflammatory responses, 40 male Kunming mice were exposed in four similar static chambers, 0 (control) three different doses (groups...
Abstract Climate change and air pollution are two intimately interlinked global concerns. The frequency, intensity, duration of heat waves projected to increase globally under future climate change. A growing body evidence indicates that health risks associated with the joint exposure can be greater than due individual factors. However, cooccurrences extremes in China remain less explored observational records. Here we investigate spatial pattern temporal trend using China’s nationwide...
Abstract Machine learning is widely used to infer ground-level concentrations of air pollutants from satellite observations. However, a single pollutant commonly targeted in previous explorations, which would lead duplication efforts and ignoration interactions considering the interactive nature their common influencing factors. We aim build unified model offer synchronized estimation pollution levels. constructed multi-output random forest (MORF) achieved simultaneous hourly PM 2.5 , 10 O 3...
Abstract Aerosol pollution is anticipated to decrease in the future, yet associated effects of reduced aerosol loading on precipitation remain insufficiently explored. Widespread reductions anthropogenic emission during COVID-19 lockdowns offer a unique opportunity understand responses changes aerosols. Based observations and regional global climate-chemistry coupled model simulations, we attribute unprecedented India 2021 lockdown decreased levels due reductions. Reduced leads northward...
Forest management is vital to the growth and development of trees at different stages. However, comprehensively capturing tree attributes determine response remains a major challenge. Therefore, this study utilized TLS technology probe forest structure information, explore effects on stem diameter, develop most appropriate taper model reveal how thinning affects size form larch during SIS SES. Larch plantations aged 16 26 years were subjected intensities treatments, 3D structural information...
Chinese olive trees (Canarium album L.) are broad-leaved species that widely planted in China. Accurately obtaining tree crown information provides important data for evaluating growth status, water and fertilizer management, yield estimation. To this end, study first used unmanned aerial vehicle (UAV) images the visible band as source of remote sensing (RS) data. Second, based on spectral features image object, vegetation index, shape, texture, terrain were introduced. Finally, extraction...
Abstract The onset of the South China Sea summer monsoon (SCSSM) has profound impacts on meteorological conditions over East Asia. However, whether interannual variability in date ozone (O 3 ) pollution remains unclear. Here, we investigate relationship between early SCSSM and late spring O southern China. Our results show notable differences surface concentrations before after during events enhanced 11.1 μg m −3 is supported by increased air temperature solar radiation 1.1 K 30.9 W −2...
In this study, we investigated the effect of inhaled mixtures volatile organic compounds (VOCs) and carbon monoxide (CO) on neuroethology. Fifty 6-week-old male Kunming mice were exposed in five similar static chambers; zero (control) four different doses VOC CO (G1–G4) for 10 consecutive days 2 h/day. The concentrations as follows: formaldehyde, benzene, toluene, xylene, 0.10 + 0.11 0.20 10.00 mg/m 3 , 0.22 0.40 20.00 1.00 1.10 2.00 100.00 5.00 5.50 500.00 respectively, which corresponded...
