• #### 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). ...
• #### 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 ...
• #### 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 ...
• #### 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 ...
• #### 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 ...
