Patterns in atmospheric carbonaceous aerosols in China: emission estimates and observed concentrations
(Copernicus GmbH, 2015)China is experiencing severe carbonaceous aerosol pollution driven mainly by large emissions resulting from intensive use of solid fuels. To gain a better understanding of the levels and trends of carbonaceous aerosol ... -
Potential for Wind-Generated Electricity in China
(American Association for the Advancement of Science, 2009)Wind offers an important alternative to coal as a source of energy for generation of electricity in China with the potential for substantial savings in carbon dioxide emissions. Wind fields derived from assimilated ... -
Prospects for shale gas production in China: Implications for water demand
(Elsevier BV, 2016)Development of shale gas resources is expected to play an important role in China's projected transition to a low-carbon energy future. The question arises whether the availability of water could limit this development. ... -
Quantifying the Uncertainties of a Bottom-Up Emission Inventory of Anthropogenic Atmospheric Pollutants in China
(European Geosciences Union, 2011)The uncertainties of a national, bottom-up inventory of Chinese emissions of anthropogenic \(SO_2\), \(NO_x\), and particulate matter (PM) of different size classes and carbonaceous species are comprehensively quantified, ... -
Recent Changes in Particulate Air Pollution over China Observed from Space and the Ground: Effectiveness of Emission Control
(American Chemical Society (ACS), 2010)The Chinese government has moved aggressively since 2005 to reduce emissions of a number of pollutants including primary particulate matter (PM) and sulfur dioxide (SO2), efforts inadvertently aided since late 2008 by ... -
Regional CO pollution and export in China simulated by the high-resolution nested-grid GEOS-Chem model
(Copernicus GmbH, 2009)An updated version of the nested-grid GEOS-Chem model is developed allowing for higher horizontal (0.5°×0.667°) resolution as compared to global models. CO transport over a heavily polluted region, the Beijing-Tianjin-Hebei ... -
Regional CO Pollution in China Simulated by the High-Resolution Nested-Grid GEOS-Chem Model
(Copernicus Publications, 2009)An updated version of the nested-grid GEOS-Chem model is developed allowing for higher horizontal (0.5°×0.667°) and vertical resolution as compared to global models. CO transport over a heavily polluted region, the ... -
A Review of Approaches to Low-Carbon Transition of High-Rise Residential Buildings in China
(Elsevier BV, 2020-10)In developing countries with a large population and fast urbanization, High-rise Residential Buildings (HRBs) have unavoidably become a very common, if not the most, accommodation solution. The paradigm of HRB energy ... -
Seasonal variability of NOx emissions over east China constrained by satellite observations: Implications for combustion and microbial sources
(Wiley-Blackwell, 2007)Observations of tropospheric column densities of NO2 obtained from the Global Ozone Monitoring Experiment (GOME) for a 3-year period (1997, 1998, and 2000) are used to derive average seasonal variations in surface emissions ... -
Soil Acidification in China: Is Controlling SO 2 Emissions Enough?
(American Chemical Society (ACS), 2009)Facing challenges of increased energy consumption and related regional air pollution, China has been aggressively implementing flue gas desulfurization (FGD) and phasing out small inefficient units in the power sector in ... -
Thermodynamic disequilibrium of the atmosphere in the context of global warming
(Springer Science + Business Media, 2015)The atmosphere is an example of a non-equilibrium system. This study explores the relationship among temperature, energy and entropy of the atmosphere, introducing two variables that serve to quantify the thermodynamic ... -
Thermodynamic Modeling Suggests Declines in Water Uptake and Acidity of Inorganic Aerosols in Beijing Winter Haze Events during 2014/2015–2018/2019
(American Chemical Society (ACS), 2019-11-04)During recent years, aggressive air pollution mitigation measures in northern China have resulted in considerable changes in gas and aerosol chemical composition. But it is unclear whether aerosol water content and acidity ... -
Top-down estimate of China's black carbon emissions using surface observations: Sensitivity to observation representativeness and transport model error
(Wiley-Blackwell, 2013)This study examines the sensitivity of “top-down” quantification of Chinese black carbon (BC) emissions to the temporal resolution of surface observations and to the transport model error associated with the grid resolution ... -
Traffic restrictions associated with the Sino-African summit: Reductions of NOx detected from space
(Wiley-Blackwell, 2007)Aggressive measures were instituted by the Beijing municipal authorities to restrict vehicular traffic in the Chinese capital during the recent Sino-African Summit. We show that reductions in associated emissions of NOx ... -
Urban form and digitalization of urban design
In the mid-18 Century, John Snow utilized spatial data analysis to trace the source of a cholera outbreak in London. His methods established the fundamental theory of using urban morphological study to solve practical urban ... -
Variations of \(O_3\) and CO in Summertime at a Rural Site Near Beijing
(Copernicus Publications on behalf of the European Geosciences Union, 2008)Large intra-season differences in mixing ratios of CO and \(O_3\) were detected at Miyun, a rural site north of Beijing, in summer 2006. Despite an increase in mean daytime mixing ratio of CO from 500 ppbv in June to 700 ... -
Will PM control undermine China’s efforts to reduce soil acidification?
(Elsevier BV, 2011)China’s strategies to control acidifying pollutants and particulate matter (PM) may be in conflict for soil acidification abatement. Acidifying pollutant emissions are estimated for 2005 and 2020 with anticipated control ... -
Year round measurements of O3 and CO at a rural site near Beijing: variations in their correlations
(Co-Action Publishing, 2010)We examine seasonal variations of carbon monoxide (CO), ozone (O3), and their relationships observed over the course of 3 yr (2005–2007) at Miyun, a rural site 100 km north of Beijing. Monthly mean afternoon mixing ratios ...
