摘要：

This paper presents an analysis of observations of methane and its two major isotopologues, CH3D and (CH4)-C-13, from the Atmospheric Chemistry Experiment (ACE) satellite between 2004 and 2013. Additionally, atmospheric methane chemistry is modeled using the Whole Atmospheric Community Climate Model (WACCM). ACE retrievals of methane extend from 6 km for all isotopologues to 75 km for (CH4)-C-12, 35 km for CH3D, and 50 km for (CH4)-C-13. While total methane concentrations retrieved from ACE agree well with the model, values of delta D-CH4 and delta C-13-CH4 show a bias toward higher delta compared to the model and balloon-based measurements. Errors in spectroscopic constants used during the retrieval process are the primary source of this disagreement. Calibrating delta D and delta C-13 from ACE using WACCM in the troposphere gives improved agreement in delta D in the stratosphere with the balloon measurements, but values of delta C-13 still disagree. A model analysis of methane's atmospheric sinks is also performed.
