Outline of Final Research Achievements

This study investigated global budget of atmospheric methane (CH4) and nitrous oxide (N2O), and inferred separate factors of their temporal changes. In the framework of a land-ecosystem and trance gas exchange model, estimations of global emissions of CH4, N2O, and biogenic VOCs were optimized. For the changes in OH which govern the CH4 sink in the atmosphere, individual controlling factors of OH changes were quantified and examined by a set of sensitivity simulations using an atmospheric chemistry model. More accurate estimation of global OH changes was also performed by our developed data assimilation system with the satellite measurements of global atmospheric chemistry. This study also investigated and tested N2O budget including emissions, photolysis, stratosphere-troposphere exchange (STE). Furthermore, underlying mechanisms and controlling factors of recent CH4 and N2O changes are revealed in detail by using past reproduction simulations (hindcasts) for CH4 and N2O.
