Antarctic and Greenland Climate Change Comparison

This data set compares global atmospheric concentration of methane from ice cores taken on the ice sheets of Antarctica and Greenland. The data come from multiple ice cores on each continent, including Greenland Ice Core Project (GRIP) and Greenland Ice Sheet Project (GISP) ice cores and the Byrd and Vostok cores from Antarctica. (The orignal dataset is located at ftp://ftp.ncdc.noaa.gov/pub/data/paleo/icecore/greenland/summit/grip/synchronization/)

本数据集对比了南极洲和格陵兰岛冰盖所采集的冰芯中全球大气甲烷浓度。数据来源于各大洲的多处冰芯，包括格陵兰冰芯项目（GRIP）、格陵兰冰盖项目（GISP）冰芯，以及南极洲的拜尔德和沃斯托克冰芯。原始数据集位于ftp://ftp.ncdc.noaa.gov/pub/data/paleo/icecore/greenland/summit/grip/synchronization/。
