SPRUCE Data-constrained Projections of Methane Fluxes in a Northern Minnesota Peatland in Response to Elevated CO2 and Warming: Modeling Archive

Study developed a data-informed process-based model using methane chamber measurement data from the SPRUCE project experiment in a northern peatland in northern Minnesota.

Study used existing manual CH4 flux measurements collected from the ambient environment from 2011-2014 and developed a data-informed process-based methane module. The module was incorporated into the Terrestrial ECOsystem (TECO) model before its parameters were constrained with multiple years of methane flux data for forecasting CH4 emission under five warming and two elevated CO2 experimental treatments at SPRUCE.

Included in this model archive are the (1) source code of the TECO model used in the study (2) the posterior distribution of parameters values, and (3) model simulated results of methane emission for different pathways under different environmental conditions.

Forecasting of CH4 emission dynamics. Green dots refer to observations from 2011-2014 which were used for model development. Blue dots indicate observations from 2015-2016 which were used for model validation. Red line is simulated mean methane emission.
