NOAA/WDS Paleoclimatology - Atmospheric CH4, Interpolar Difference and Excesss Methane Data from the WAIS Divide, GISP2, and NEEM Ice Cores, Last Glacial Maximum and Deglaciation

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 26, 2026 | Last Modified: 2023-10-05T00:00:00.000+00:00

This archived Paleoclimatology Study is available from the NOAA National Centers for Environmental Information (NCEI), under the World Data Service (WDS) for Paleoclimatology. The associated NCEI study type is Ice Core. The data include parameters of climate forcing|ice cores with a geographic location of Greenland. The time period coverage is from 48100 to 11300 in calendar years before present (BP). See metadata information for parameter and study location details. Please cite this study when using the data.
