摘要:	研究期間：10101~10112;In order to clarify the intercontinental and regional transport (for instance, acid pollutants, Asian dust, biomass burning and mercury), and to collect the atmospheric baseline data, the Lulin Atmospheric Background Station (LABS, 2862 m MSL), located at Mt. Lulin in central Taiwan, has been operated since 13 April 2006. This project integrates the researchers in the fields of precipitation chemistry, gas chemistry, aerosol chemistry, atmospheric mercury and radiation to test and maintain the instruments, conduct data analysis and construct long-term database. Up to now, total on-site maintenances (includes regular and mobile) are 50 times. The data acquisition rate for aerosols, radiation and meteorological instruments are greater than 90 %, whereas atmospheric mercury and trace gases instruments shows lower rates, due to their complexities. During the project conducting period of January–October in 2012, the average concentrations of CO, O3 and PM10 are about 131.1 ppb, 43.1 ppb and 9.2 g m-3, respectively. The average pH value of precipitation is 5.76. The average concentrations of mercury such as GEM, RGM and PHg are about 1.55 ng m-3, 14.33 pg m-3 and 1.79 pg m-3, respectively. Monthly variation shows the high concentration of pollutants generally occurred during spring time, especially in March. Integrating trajectory analysis and chemical component analysis, we suggest the high concentration events are most likely associated with the biomass burning from SE Asia. The atmospheric background values for CO, O3, and PM10 in Lulin are estimated to be about 115.5 ppb, 36.5ppb, and 4.1 g m-3, respectively. In addition, we have established intensive international collaborations with USEPA, NOAA, NASA, Japan, and EU countries. We have also participated international experiments or campaigns including UNEP/ABC/EAREX, 7-SEAS, BASE-Asia, and Japan Mt. Fuji Project. The LABS is now part of global networks, for instance, American Mercury network/AMNET, NASA/AERONET, NASA/ MPLNET, NOAA/GMD/CCGG sampling network.
