 note = {P(論文), 昭和基地における大気中のメタン濃度の高精度連続観測は1988年2月に開始された。メタン濃度の日変化は1年を通して全く観測されなかったが, 数日周期で振幅が最大でも5ppbv程度の不規則な変動は見られた。メタン濃度は夏に最低値, 冬に最高値が出現するきれいな季節変化をしており, 平均振幅は30ppbvであった。メタン濃度は経年的に増加しており, 1988年から1992年までの平均増加率は10.4ppbv yr^<-1>であった。, Precise and continuous measurement of atmospheric CH_4 concentration was initiated at Syowa Station in February 1988. A diurnal variation of CH_4 concentration was not observable throughout the year, but irregular variations with periods of a few days and an amplitude of about 5ppbv at most were sometimes observed. A regular seasonal cycle of CH_4 concentration with a winter maximum and a summer minimum was clearly seen. The peak-to-peak amplitude of the averaged seasonal cycle was 30ppbv. CH_4 concentration was secularly increasing; the mean rate of the increase between 1988 and 1992 was 10.4ppbv yr^<-1>.},
