Atmospheric Methane and Nitrous Oxide of the Late Pleistocene from Antarctic Ice Cores
International audience The European Project for Ice Coring in Antarctica Dome C ice core enables us to extend existing records of atmospheric methane (CH4) and nitrous oxide (N2O) back to 650,000 years before the present. A combined record of CH4 measured along the Dome C and the Vostok ice cores de...
