Short summary

The relative ratio of wetland methane (CH₄) emission pathways determines how much CH₄ is oxidized before leaving the soil. We found an ebullition modeling approach that has a better performance in deep layer pore water CH₄ concentration. We suggest using this approach in land surface models to accurately represent CH₄ emission dynamics and response to climate change. Our results also highlight that both CH₄ flux and belowground concentration data are important to constrain model parameters.
