Top: Time series of observed (black), posterior (blue) and prior (dark green) average CH4 mole fraction. For the prior simulations, fluxes were used to calculate CH4 mole fractions, while for the posterior simulations, CH4 was calculated using fluxes that were adjusted for optimal agreement with atmosphereic observations. Units are ppb (10-9 mol mol-1).
Bottom: Time series of observed (black), posterior (blue) and prior (dark green) average δ13C-CH4. For the prior simulations, fluxes were used to calculate δ13C-CH4, while for the posterior simulations, δ13C-CH4 was calculated using fluxes that were adjusted for optimal agreement with atmosphereic observations. Units are permil (‰).
