초록 Korea Global Atmosphere Watch Center (KGAWC), which is located in Anmyeondo and, belongs to the Korea Meteorological Administration (KMA), measures sulfur hexafluoride (<TEX>$SF_6$</TEX>) in every hour since 2007. In this study, <TEX>$SF_6$</TEX> observed in 2007 are discussed. A gas chromatograph-electron capture detector (GC-ECD) with pre-cooled device is applied during the observation, and produced data are qualified by means of periodic calibration with <TEX>$SF_6$</TEX> standard gas made by Korea Research Institute of Standard and Science (KRISS). <TEX>$SF_6$</TEX> has been greatly paid attention since Kyoto protocol because of its high global warming potential(GWP) with 22,200 times of <TEX>$CO_2$</TEX> in the period of 100 years. It is a man-made compound and has been usually used for gas insulation since 1970s and for etching process in the information technology-based industry since 1990. Average mixing ratio of <TEX>$SF_6$</TEX> in 2007 was 6.65 pmol/mol at Anmyeondo. According to the GAW report published in 2008, average mixing ratio of <TEX>$SF_6$</TEX> in the atmosphere is continuously growing. At present, the average mixing ratio of <TEX>$SF_6$</TEX> in the atmosphere is known to be approximately 6.25 pmol/mol at global observatory. <TEX>$SF_6$</TEX> value in Anmyeondo shows 0.40 pmol/mol greater than that of the Mauna Loa observatory in 2007.
