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 ...
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 ...
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 ...
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 ...
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). ...
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 ...
