Summary
Abstract: The atmospheric trace gas, methane (CH4), affects the radiative heat balance of the earth. The sources of atmospheric methane are not well understood. Large air samples (1000-1400 litres) of methane are collected from a compressor system at Arrival Heights annually (since 1989) and samples are analysed for methane concentrations, the isotopic ratios of 14C/ 13C and 13C/12C and the characteristics ...
