Title: ACE-Asia Database_Gosan HiVol_1.2 This database includes the total suspended particulate (TSP) matter mass concentrations collected from sampling at the Gosan Supersite (33.17E, 126.10N) located on Jeju Island, South Korea during March 31 to May 3, 2001 as part the ACE-Asia Experiment. The times and dates included in this database are UTC. Please direct any questions about the data to: Rachelle Duvall Water Science and Engineering Laboratory RM 152 660 N. Park Street Madison, WI 53706 (608) 262-4322 (office) (608) 262-0454 (fax) Email Address: rmduvall@students.wisc.edu TSP samples were collected each day for 24-hrs using a High Volume Sampler (Andersen Instruments). TSP Mass was measured at a Temperature of 70 C (68-73) and Rh of 38 %RH (30-40%). Columns 1 and 2 of the data set contain the start and stop sampling times in UTC for the corresponding sample number. The mass uncertainty was calculated using the following formula: SQRT (STDev Initial weight^2+ STDev Final Weight ^2). A 5% uncertainty was accounted for in the mass measurement resulting from uncertainty in the sampler airflow rate measurements. Rachelle Duvall Revised April 2, 2003
