This special issue belongs to the section "Air Quality". If China fulfills Xi’s goal, it could prevent 0.4 to 0.7 degrees (0.2 to 0.4 degrees Celsius) further warming for the world, according to “very rough estimates” by MIT management professor John Sterman, who models and tracks emission reductions and pledges with Climate Interactive. That was almost twice as much as the United States and three times as much as the European Union. Definitely you won’t miss the golden opportunity to look for the places in Shanghai that have the new year’s most festive atmosphere and rich traditional customs for Chinese New Year’s Celebration. Atmosphere, an international, peer-reviewed Open Access journal. Results showed that annual mean AV of the 31 PCCs in China were 14.30 km, with a declining rate of −1.07 km/decade. Maybe this is your first time to visit China during its Spring Festival, the biggest national holiday in China just like Christmas in the west. Institute of Environment and Climate (ECI), Jinan University, Guangzhou, China, School of Environment and Energy, South China University of Technology, Guangzhou, China, (This article belongs to the Special Issue, Rate coefficients at ambient temperature and atmospheric pressure for the reaction of ozone with 2-methoxypropene (2-MPE) and 2-ethoxypropene (2-EPE) were determined in an evacuable 100 L Teflon reaction chamber using absolute and relative rate methods. The authors combined this with China’s past and present emissions to estimate, for the first … But the public health benefits aren't so simple to calculate. Prof. Dr. Bin YuanProf. Download this stock image: Atmosphere London celebrates Chinese New Year in Chinatown London, England - 06.02.11 - CFPBDH from Alamy's library of millions of … In the recent decades, many rapidly-developing economic regions have experienced increasingly-significant air pollution, arousing great public concern. We also reveal that residents’ activities are the primary direct socioeconomic factors on AV. Authors may use MDPI's In addition to the impact of pollutant emissions, haze pollution is connected with meteorology and climate change. In recent years, road space rationing policies have been increasingly applied as a traffic management solution to tackle congestion and traffic emission problems in big cities. Our dedicated information section provides allows you to learn more about MDPI. China time now. Coal is the biggest carbon dioxide emitter of power sources. “That’s a lot,” Sterman said. A notable increasing trend in annual HDs over the majority of SCC region was found during 1980–1995, then the trend sharply reversed during 1996–2005, while it increased, fluctuating at some cities after 2006. China Weather Map. Please note that many of the page functionalities won't work as expected without javascript enabled. The anomalies of thermal forcing of WPWP could induce to the changes of East Asian winter monsoonal winds and the vertical thermal structures in the troposphere over the CEC region. Greenpeace executive director Jennifer Morgan called it “an important signal” that showed climate change is “top of agenda for China.”. Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). To create a strong connection between Chinese businesses and the global market for natural refrigerants, ATMOsphere China will be simultaneously translated in English and Chinese.. We are excited to work with Chinese government and leading … The inter-annual variations of HDs in 18 main cities revealed that Zigong, Neijiang, and Yibin, which are located in the southern of SCB, have been the most polluted areas over the SCC region in the past decades. Calling for a “green revolution,” Xi said the coronavirus pandemic had shown the need to preserve the environment. Subscribe to receive issue release notifications and newsletters from MDPI journals, You can make submissions to other journals. This study hopes to help the public fully understand the characteristics of AV and make recommendations about improving the air environment in China’s urban areas. In this paper, based on multi-source dust data including ground observations, satellite monitoring, and reanalysis products, as well as air quality index (AQI) and the mass concentrations of PM, This study analyzed the long-term variations and trends of haze pollution and its relationships with emission and meteorological factors using the haze days (HDs) data derived from surface observation stations in Sichuan-Chongqing (SCC) region during 1980–2016. Xi's announcement during a speech Tuesday, Sept. 22, 2020, to the U.N. General Assembly is a significant step for the world's biggest emitter of greenhouse gases and was immediately cheered by climate campaigners. There are few studies paying attention to the effect of nonlocal license plate restrictions on air quality in Shanghai. Based on the interannual change analyses of meteorological and environmental observation data from 1981 to 2010, we studied the relationship between the winter haze frequency in. However, the scope and, Aerosols are an important factor affecting air quality. Using correlation analysis between HDs and emission and meteorological factors during different periods, we found that the variability of local precipitation days (PDs), planetary boundary layer height (PBLH), near-surface wind speed (WS), and relatively humidity (RH) play different roles in influencing the haze pollution change during different historical periods. Existing studies on the effect of traffic policy on air quality have mainly focused on the odd–even. Aromatics (79.5~81.4%) were the largest group in auto-painting factories, while oxygenated VOCs (82.0%) and heavy alkanes (68.7%) were dominant in gravure printing and offset printing factories, respectively. The term “carbon neutrality” means releasing no additional CO2 into the atmosphere, though technically it allows countries to keep emitting if they ensure that an equal amount is captured again in some form. Concentrations of 86, Industrial emission is an important source of ambient volatile organic compounds (VOCs) in Wuhan City, Hubei Province, China. Please visit the Instructions for Authors page before submitting a manuscript. To investigate the impact of such a policy on the residents’ exposure to pollutants, CO concentration and Air Quality Index (AQI) were compared during January and February in 2015, 2016 and 2017. We found: (1) the fine size of PM (PM, To explore the polychlorinated biphenyl (PCB) pollution characteristics of atmospheric particles, influential factors, and dry deposition fluxes, 28 PCB congeners were examined over a 2-year period in the environment of an isolated island in Fujian Province. The United States has so far not set such a goal. Once you are registered, click here to go to the submission form. Seasonal and annual mean values of AV, percentage of ‘good’ (≥20 km) and ‘bad’ AV (<10 km), cumulative percentiles and the correlation between AV, socioeconomic factors, air pollutants and meteorological factors were analyzed in this study. The goal will be a challenge for China, which relies heavily for its electricity on coal, one of the most carbon-intensive fossil fuels. Industrial emission is an important source of ambient volatile organic compounds (VOCs) in Wuhan City, Hubei Province, China. Several conclusions can be made: (1) CO concentration was higher on ground-level roads on the restriction days than those in the nonrestriction days; (2) the extension of the restriction period exposed the commuters to high pollution for a longer time on the ground, which will do harm to them; and (3) the nonlocal vehicle restriction policy did play a role in improving the air quality in Shanghai when extending the evening rush period. To more effectively reduce population exposure to PM, In recent years, road space rationing policies have been increasingly applied as a traffic management solution to tackle congestion and traffic emission problems in big cities. In this study, long-term AV trends (from 1957–2016, excluding 1965–1972) and spatial characteristics of 31 provincial capital cities (PCCs) of China (excluding Taipei, Hong Kong, and Macau) were investigated. The China Weather Map below shows the weather forecast for the next 12 days. Regression discontinuity (RD) was used to test the validity of nonlocal vehicle restriction on mitigating environmental pollution. We collected 53 VOC samples from petrochemical, surface coating, electronic manufacturing, and gasoline evaporation using stainless canisters to develop localized source profiles. Nine air-quality monitoring stations (AQMS) were selected as the central points. The second ATMOsphere China conference will take place in Shanghai on 11-12 April 2019, corresponding with China Refrigeration (9-11 April). Together with this, ground meteorological variables were also used throughout the investigation period: 1 December 2015 to 30 November 2016. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. “Emissions that don’t happen between now and 2030 are going to reduce warming a lot more than the same emission reductions after 2060,” Sterman said. Find support for a specific problem on the support section of our website. China has gradually explored a set of 'refined understanding–efficient control–scientific regulation' as the mainline of its air pollution prevention and control system to tackle the worldwide conundrum of air pollution prevention and control under the backdrop of rapid economic development. (3) The concentration of PM2.5 and PM10 showed no significant difference between all the green spaces and the control group. The new study quantifies all the gases and particles currently in the atmosphere that are having an effect on global temperature, and which can be traced back to human activity.

In sunny and breeze weather conditions, PM2.5 and PM10 concentration increased with the wind velocity and humidity, and decreased with the temperature. A better understanding of the characteristics and the factors affecting AV can help the public and policy makers manage their life and work. Long-Term Atmospheric Visibility Trends and Characteristics of 31 Provincial Capital Cities in China during 1957–2016. The results showed that: (1) Location, time, wind velocity, temperature and humidity had highly significant effects on the concentration of PM2.5 and PM10. The Golden Week will be the first major holiday since the country brought the COVID-19 outbreak under control. (AP Photo/Sam McNeil, File), Connect with the definitive source for global and local news, which relies heavily for its electricity on coal. A special issue of Atmosphere (ISSN 2073-4433). Correction: Fu et al. Air pollution levels have dropped dramatically as power plants and factories have slowed down — potentially saving lives. Correlation analysis showed that impact factors (e.g., urban size, industrial activities, residents’ activities, urban greening, air quality, and meteorological factors) contributed to the variation of AV. However, pledges are not the same as actions. With China, the 30 countries that have some kind of carbon neutrality pledges, account for about 43% of the world’s carbon dioxide emissions from the burning of fossil fuels. Christmas atmosphere is seen across the world. You seem to have javascript disabled. This Special Issue is open to all publications on air quality in China.

Select from the other forecast maps (on the right) to view the temperature, cloud cover, wind and precipitation for this country on a large scale with animation. The above results will provide a theoretical basis and practical methods for the optimisation of urban green space structures for improving urban air quality effectively in the future. The second ATMOsphere China conference will take place in Shanghai on 11-12 April 2019, corresponding with China Refrigeration (9-11 April). The joint effect of sharp increase of anthropogenic emissions, reduced PDs and WS intensified the haze pollution in SCB during 1980–1995. In addition, a remarkable increasing trend was found in winter since 2006. View the latest China news and videos, including politics, travel and business headlines. Eleven types of green space with different structures were selected for investigating the relationships between atmospheric particulate matter (PM) concentration and green spaces with different vegetation structure, based on the “matrix effect” of environmental factors, i.e., location, time, wind velocity, temperature, humidity and area to the concentration of PM2.5 and PM10 in the green spaces. Subsection China. UNITED NATIONS (AP) — Chinese President Xi Jinping says his country will aim to stop adding to the global warming problem by 2060. Alkanes were the dominant VOC group, with, Aerosols are an important factor affecting air quality. Along with strengthened scientific understanding on the causes, formation processes and control mechanisms of air pollution in China, the supportive role of atmospheric research on air pollution control has been greatly improved. Manuscripts can be submitted until the deadline. In this paper, based on multi-source dust data including ground observations, satellite monitoring, and reanalysis products, as well as air quality index (AQI) and the mass concentrations of PM 10 and PM 2.5 at 367 urban stations in China for 2015, we examined the temporal and spatial characteristics of the impacts of the Taklimakan dust events on downstream urban air quality in China. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website. Out of control Chinese space station expected to fall to Earth within several hours. That was almost twice as much as the United States and three times as much as the European Union. Our Atmosphere at China World Summit Wing, Beijing which serves vast variety of beverages is the ideal venue for chilling out completely. Chinese space station enters the atmosphere Most of the space station likely burned up as it entered Earth's atmosphere while remaining debris landed in the South Pacific Ocean, authorities said. Our study revealed that the thermal forcing of the WPWP could have a modulation on air environment change in China. In 2006 and 2007, PCB concentrations ranged from 1.12 to 87.32 pg m, To evaluate air pollution and the public health burden of heavy metals in PM, The authors would like to correct the published article[...], The statements, opinions and data contained in the journal, © 1996-2020 MDPI (Basel, Switzerland) unless otherwise stated. The largest polluting countries not on the list are the United States, India, Russia, Iran, Saudi Arabia, Indonesia, South Africa, Turkey, Brazil and Australia. The reentry and landing of a new Chinese spacecraft Friday marked a step toward the country sending astronauts to the moon and deep space. Xi’s announcement during a speech Tuesday to the U.N. General Assembly is a significant step for the world’s biggest emitter of greenhouse gases. China’s experimental space-lab Tiangong-2 is scheduled to leave orbit and re-enter Earth’s atmosphere on July 19. Atmosphere is an international peer-reviewed open access monthly journal published by MDPI. The AV of the 31 PCCs declined dramatically between 1973–1986, then plateaued between 1987–2006, and rebounded slightly after 2007. Six distances of 1, This case study was conducted to quantify the effects of urban greenspace patterns on particle matter (PM) concentration in Zhengzhou, China by using redundancy and variation partitioning analysis. In addition to the impact of pollutant emissions, haze pollution is connected with meteorology and climate change. Carbon dioxide’s more than 100-year lifetime in the air makes earlier emission cuts more effective than promises in the future, he said. “A big shift for curbing emissions and a significant step forward in international cooperation” U.N. climate chief Patricia Espinosa said. Deterioration of air quality in China has been reversed, but new problems such as elevated ozone levels emerge. Alkanes were the major constituents observed in the source profile from the petrochemical industry. In this study, green spaces in Baoji city were classified into different patterns on the basis of vegetation structural parameters, i.e., horizontal. Section BBC News. China time zone and map with current time in the largest cities. Dr. Zibing YuanGuest Editors. Several other major emitters have set earlier deadlines, with the EU aiming to be carbon neutral by 2050. ATMOsphere China 2019. Additionally, some suggestions are mentioned in order to improve air quality and passenger health and safety. “We aim to have CO2 emissions peak before 2030 and achieve carbon neutrality before 2060,” he said. A series of stringent air pollution control strategies has been promulgated in different countries, e.g., the Air Pollution Prevention and Control Action Plan issued by State Council of China in September 2013. In the winter with anomalously warm SST over the WPWP, the near-surface winds were declined, and vertical thermal structure in the lower troposphere tended to be stable over the CEC-region, which could be conducive to air pollutant accumulation leading to the more frequent haze occurrences especially the heavy haze regions of Yangtze River Delta (YRD) and Pearl River Delta (PRD); In the winter with the anomalously cold WPWP, it is only the reverse of warm WPWP with the stronger East Asian winter monsoonal winds and the unstable thermal structure in the lower troposphere, which could attribute to the less frequent haze pollution over the CEC region. The panel noted that it would take the destruction of 13 million large fridges a year to account for 13,000 tons of CFC-11 released in the atmosphere.
