Abstract
An Aerodyne Aerosol Mass Spectrometer (AMS) was deployed during the Aerosol Characterization Experiment-Asia (ACE-Asia) field campaign on board the Center for Interdisciplinary Remotely Piloted Aircraft Studies (CIRPAS) Twin Otter aircraft to measure the size- resolved chemical composition of sub-micron aerosols in the outflow from Eastern Asia. Research flights were carried out from March 31-May 1, 2001 in an area that covered 127 °E-135 °E and 32 °N-38 °N. Valid data from the AMS were obtained during 15 out of a total of 19 research flights. During the mission, the AMS measured distinct layers (from the boundary layer to ~ 3700 m) of sub-micron aerosols composed of sulfate, ammonium, and organics as the major non-refractory components, separated by layers with much lower aerosol concentrations. Sulfate and organics mass concentrations of up to 10 µg m-3 and 13 µg m-3, respectively, were measured in some pollution layers. Back trajectory analysis shows that the polluted layers originated in urban and industrial areas of China and Korea. The mass-weighed size distribution of the sub-micron sulfate was relatively constant from day to day and layer to layer, with an
