Progress Reports

ABSTRACT

We conducted research aimed at further understanding atmospheric methane (CH4), carbon monoxide (CO), and non-methane (C1-C5) hydrocarbons (NMHCs). We made measurements of mixing ratios in atmospheric CH4, CO and NMHCs as well as measurements providing supporting data such as stable and radiocarbon isotope measurements in these trace gases to answer questions posed by their global distribution and changes in their mixing ratios in the atmosphere.
