Quoted from: Gilhespy, Sarah L., Steven Anthony, Laura Cardenas, David Chadwick, Agustin del Prado, Changsheng Li, Thomas Misselbrook et al. "First 20 years of DNDC (DeNitrification DeComposition): model evolution." Ecological modelling 292 (2014): 51-62. 

NEST-DNDC was developed to quantify CH4 fluxes in permafrost conditions. The model simulates the biophysical and biogeochemical processes in plant communities and up-scales them to the ecosystem scale based on the areal fractions of the plant communities in the ecosystem (Zhang et al., 2012). NEST-DNDC was created by integrating DNDC with a permafrost model, the Northern Ecosystem Soil Temperature (NEST) model (Zhang et al., 2003) and is capable of modelling the interactions between soil thermal-hydrological conditions and biogeochemical processes in permafrost soils (Zhang et al., 2012). NEST-DNDC is also able to simulate upland and wetland ecosystems without permafrost. The modelled soil profile can contain many different soil textures and layers of varying thickness and gravel content. The model can be applied to a wide range of ecosystems from forest to tundra, as it can model an upper and understory of woody plants, a layer of sedges or grass and a layer of mosses.
