Atmospheric measurements combined with inverse atmospheric models can provide independent top-down estimates of greenhouse gas (GHG) emissions. This is important in particular for N2O and CH4, for which considerable uncertainties of the bottom-up inventories exist (uncertainty estimates of bottom-up emissions reported to UNFCCC: CH4: 30%; N2O >100% for annual country totals). According to UNFCCC inventories, CH4 and N2O contributed 'only' 8% and 7%, respectively, of total GHG emissions of EU-15 countries (2007). However, the reported reductions of total GHG emissions (1990-2007: -199 Tg CO2 eq) are mainly attributed to CH4 (-133 Tg CO2 eq) and N2O (-105 Tg CO2 eq).
