The dataset contains 14 Excel files of data corresponding to Figures 3 to 6 and Figures S1 to S10 in the support information in ‘Linking biogeochemical and hydrodynamic processes to model methane fluxes in shallow, tropical floodplain lakes’. The dataset covers measured data, simulation results by the Arctic Lake Biogeochemical Model (ALBM) and simulation results by the 3-Dimensional coupled Hydrodynamic-Aquatic Ecosystem Model (AEM3D) during the simulation periods in the manuscript. The AEM3D results were prepared as part of the input data of ALBM. The dataset includes: 1. Profiles of dissolved oxygen concentrations measured by moored sensors every 10 minutes and corresponding ALBM simulated profiles of dissolved oxygen concentrations. 2. Methane concentrations sampled manually at intermittent times during each simulation period, and corresponding ALBM simulated methane concentrations. 3. ALBM simulated methane concentrations at 5-minute intervals.4. Diffusive methane fluxes measured by chambers collecting ...
