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 ...
