Summary
Abstract: This data represents one thousand years of atmospheric methane concentrations.
Methane concentrations was measured in air bubbles from 1008-1980 in Antarctic
ice cores, and from 1075-1885 in Greenland ice cores. Air in firn samples from
1978 to 1993 are also included as well as archived air samples from Cape Grim,
Tasmania for the years 1978-1995.
