Assessing nitrogen controls on carbon, water and energy exchanges in major plant functional types across North America using a carbon and nitrogen coupled ecosystem model

A carbon and nitrogen coupled dynamic vegetation ecosystem model (CLASS-CTEMN+) was used to assess the effects of nitrogen controls on simulated carbon, water and energy exchanges in a range of vegetation ecosystems. Standardized meteorological forcing data and eddy covariance flux measurements of carbon, water and energy from 32 FLUXNET sites covering eight major plant functional types (PFTs) across North America were used in the analysis. Two …
