Arctic Soil Methane Production Model Output from PFLOTRAN Simulations

Model output from 2012-2022 NGEE Arctic project simulations of biogeochemical cycling in polygonal permafrost soils. The archive contains simulation and analysis code, plus eight netCDF data files generated by the PFLOTRAN geochemical model, parameterized using incubation measurements from northern Alaska. The work was supported by the Department of Energy's Office of Biological and Environmental Research.

Use Cases

• Analyze simulated iron cycling dynamics over repeated oxic-anoxic cycles to understand redox processes.
• Compare modeled methane production and carbon dioxide production against incubation measurement data.
• Use the parameterized model to simulate coupled iron and carbon cycling under different initial soil pH conditions.
• Study the interaction between hydrological dynamics and biogeochemical cycles in reducing methane production.

Strengths

• Model parameterized using real incubation measurements from NGEE Arctic's 10-year research effort (2012-2022).
• Contains eight distinct netCDF output files from the PFLOTRAN simulations for analysis.

Limitations

• Model output is specific to simulated conditions of polygonal tundra in northern Alaska, limiting direct geographic generalizability.
• Requires compiled versions of specialized software (Alquimia interface, NGEE Arctic fork of PFLOTRAN) to run the provided code.
