Antarctic and Greenland Climate Change Comparison

Abstract: 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.摘要：本数据集对比了取自南极与格陵兰冰盖的冰芯所记录的全球大气甲烷浓度。数据源自两大洲的多根冰芯，包括格陵兰冰芯计划（Greenland Ice Core Project, GRIP）、格陵兰冰盖计划（Greenland Ice Sheet Project, GISP）的冰芯，以及南极的伯德冰芯（Byrd cores）与沃斯托克冰芯（Vostok cores）。
