Short summary

We compare lake models with different complexity focusing on the key factors (e.g., eddy diffusivity) which can have an influence on the distribution of the dissolved gases in water. For the first time, we compare the biogeochemical modules in the ALBM and LAKE models. The result showed a good agreement with observed data (O₂), but not for CO₂. It indicates the need to improve the representation of physical and biogeochemical processes in lake models.
