The results of an optimisation of inter-annual
methane sources and sinks calculated by inversion of atmospheric observations
are presented and analysed for the 1984-2003 period. We focus our presentation
on sources trend and inter-annual variability. Comparisons with bottom-up
estimates are presented for biomass burning and wetlands emissions (only in the
poster).
