Methane Concentrations from the WAIS Divide Ice Core (WDC06A), 60 to 11,300 ybp

This data set contains a high-resolution history of atmospheric methane (CH4) concentrations in parts per billion (ppb) from approximately 60 to 11,300 years before present (ybp), obtained in 2010 from the West Antarctic Ice Sheet (WAIS) Divide Ice Core WDC06A. Gas age is derived from the WDC06A-5 ice age scale. Data are available via FTP as a Microsoft Excel file (.xlsx).本数据集包含高分辨率的大气甲烷（atmospheric methane，CH₄）浓度记录，浓度单位为十亿分率（parts per billion，ppb），时间跨度覆盖距今约60至11300年前（before present，ybp），相关数据于2010年取自南极冰盖分水岭（West Antarctic Ice Sheet，WAIS）冰芯WDC06A。气体年龄基于WDC06A-5冰龄标尺推导得到。 数据可通过文件传输协议（File Transfer Protocol，FTP）获取，格式为Microsoft Excel（.xlsx）文件。
