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 entire simulation was conducted in Linux environment. Supercomputing resources were provided by the Rosen Center for Advanced Computing at Purdue University. The input data, output data and visualizations were processed using IDL language. The summary.xlsx can be opened by the Microsoft EXCEL 2010 or later version. Flux data like *.sav can be opened using IDL.

This dataset supports the manuscript "Uncertainty Quantification of Global Net Methane Emissions from Terrestrial Ecosystems Using a Mechanistically-based Biogeochemistry Model" currently under review. Before reusing this data, please contact the authors for recent updates.
