Abstract: Several inverse modelling investigated global CH4 sources. These studies optimized emissions from larger global regions or from different source categories, and focussed on shorter timescales (1-2 years) or climatological averages. In this article we summarize some recent inverse modelling studies which further extend our view on the global and regional CH4 budget: (1) Based on the atmospheric zoom model TM5, Bergamaschi et al. [2005] presented a coupled global-European inversion to derive CH4 emission estimates for individual European countries. (2) Recent satellite measurements from SCIAMACHY now provide comprehensive views on the global CH4 distribution [Frankenberg, et al., 2006; Frankenberg, et al., 2005]. We discuss some key results from a recent analysis based on TM5 inverse simulations [Bergamaschi, et al., 2006]. (3) The inter-annual variablity of CH4 sources and sink during 1984-2003 has been investigated in a recent study by Bousquet et al. [2006]. Key results of this study will be summarized.
