AB: The emissions of trace gases and aerosol in Mega-cities and the subsequent photochemical processing are of great current interest in developing pollution control strategies but there is still a significant lack of data from many large urban centers. From August 1 through August 27, 2005, a measurement campaign was carried out on the Peking University campus in Beijing, China. This period included extended episodes with high temperatures, high humidity and extremely poor air quality as well as episodes with cooler, clear dry air. As part of this campaign, a wide range of VOCs and oxygenated VOCs were measured by an online GC-MS system. Results of those measurements, as well as comparisons with ambient air grab samples analyzed by the Peking University canister-sampling program, will be presented. Hydrocarbon emission profiles will be compared with those from an average city in the U.S. In addition we will look at the formation of secondary species such as oxygenated VOCs and peroxyacyl nitrates.
