Impacts of Permafrost Degradation on Nitrous Oxide Emissions

Simulations cover northern high-latitude terrestrial ecosystems from 1969 to 2019 at a spatial resolution of 0.5-degree x 0.5-degree. Annual gridded outputs are reported in units of mg N m-2 yr-1.

The dataset was generated using the Terrestrial Ecosystem Model (TEM), a process-based biogeochemical model that explicitly represents terrestrial carbon and nitrogen cycling and incorporates permafrost-related processes. Two simulation scenarios are included: a baseline simulation and a permafrost-thaw simulation. For each scenario, annual gridded outputs include summed N2O net emissions and summed N2O production.
