Quantification of methane (CH4) emissions from wetlands and its sinks from uplands is still fraught with large uncertainties. Here, a methane biogeochemistry model was revised, parameterized and verified for various wetland ecosystems across the globe. We used this model to extrapolate in global scale to estimate the methane emission and consumption during 1950-2012. The all simulation was conducted in Linux environment. The supercomputing is provided by the Rosen Center for Advanced Computing at Purdue University. The input data, output data and visualizations were processed using IDL language. In this data archive, we provide all data used in visualization inside the manuscript.
