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 ...
Ozone Air Quality During the 2008 Beijing Olympics: Effectiveness of Emission Restrictions
(Copernicus Publications, 2009)
A series of aggressive measures was launched by the Chinese government to reduce pollutant emissions from Beijing and surrounding areas during the Olympic Games. Observations at Miyun, a rural site 100 km downwind of the ...
Multiple effects and uncertainties of emission control policies in China: Implications for public health, soil acidification, and global temperature
(Elsevier BV, 2011)
Policies to control emissions of criteria pollutants in China may have conflicting impacts on public health, soil acidification, and climate. Two scenarios for 2020, a base case without anticipated control measures and a ...
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 ...
Black carbon and its correlation with trace gases at a rural site in Beijing: Top-down constraints from ambient measurements on bottom-up emissions
(Wiley-Blackwell, 2011)
The mass concentrations of black carbon (BC) were measured continuously at Miyun, a rural site near Beijing, concurrently with some trace gases (CO, CO2, NOy, SO2) during the nonheating seasons of 2010 (April to October). ...
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 ...
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 ...
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 ...
