Short summary

A new process-based modelling framework, FLaMe-v1.0 (Fluxes of Lake Methane version 1.0), is developed to simulate methane (CH₄) emissions from lakes at large scales. FLaMe couples the dynamics of organic carbon, oxygen and methane in lakes and rests on an innovative, computationally efficient lake clustering approach for the simulation of CH₄ emissions across a large number of lakes. The model evaluation suggests that FLaMe captures the sub-annual and spatial variability of CH₄ emissions well.
