Analysis of nitrogen controls on carbon and water exchanges in a conifer forest using the CLASS-CTEMN+ model

A carbon (C) and nitrogen (N) cycle-coupled model, CLASS-CTEMN+ was developed by incorporating soil and plant N cycling algorithms in the Canadian Land Surface Scheme (CLASS) and the Canadian Terrestrial Ecosystem Model (CTEM), used in the Canadian Global Climate Model. Key soil and plant N cycling processes incorporated in the model include biological fixation, mineralization, nitrification, denitrification, leaching and N controls on plant …
