Purpose: Restoration of drained and extracted peatlands can potentially return them to carbon (C) sinks, thus acting as significant climate change mitigation. However, whether the restored sites will remain C sinks or switch to sources with a changing climate is unknown. Therefore, we adapted the CoupModel to simulate soil atmosphere exchanges and the associated ecosystem CO2 fluxes of a restored bog.
Abstract: The model outputs were first evaluated against three years (representing 14–16 years post restoration) of eddy covariance measurements of net ecosystem exchange (NEE), surface energy fluxes, soil temperature profiles, and water table depth data. A sensitivity analysis was conducted to evaluate the response of the simulated CO2 fluxes to the thickness of the newly grown mosses. The validated model was then used to assess the sensitivity of changes in climate forcing. CoupModel reproduced the measured surface energy fluxes and showed high agreement with the observed soil temperature, water table depth, and NEE data.
Supplemental Information Summary: The version of the CoupModel used to run the model simulations, including the source code is hosted on Zenodo (https://zenodo.org/record/3547628) and the executed CoupModel is available at www.coupmodel.com.
