Abstract
Pacific Rim countries monitoring transported yellow dust (YD) from East Asia [Aerosol Characterization Experiment in Asia (ACE-Asia)], we made measurements of PM 2.5 and PM 10 at the Shi-Men site located on Taiwan's northern tip from March to May 2001. Herein we report the results from those measurements. The average mass concentrations of PM 10 were 133, 103, and 49 gm 3 -A method of reconstructed mass shows the resolved mass fractions in PM 10 for April average, May average, and non-YD average account for 63, 69, and 72%, respectively and those for PM 2.5 are 83, 94, and 91%, respectively. The NOAA HYSPLIT back-trajectory model shows that April YD airflow came from the Gobi Desert in China via a relatively un-polluted inland route, while the May YD airflow transported along the industrial coastal areas in China. This difference in the transport path between April and May dust events may account for the difference in their aerosol compositions.
