Title: Evaluating the vegetation phenology/growth and its impact on fluxes in Ent DGTEM Abstract: The Ent Dynamic Global Terrestrial Ecosystem Model (DGTEM), is a new DGTEM for coupling the fluxes of water, energy, carbon and nitrogen between land surface and climate models, for simulating seasonal growth and decay of vegetation, and for simulating decadal- to century-scale vegetation cover change. This study shows the site-level evaluation of vegetation phenology, carbon allocation, and growth in the Ent DGTEM, and the performance of the Ent coupled to the NASA GISS land surface model at the global scale forced by Global Soil Wetness Project-2 (GSWP2) meteorology. Site-level simulations forced with Fluxnet meterological data are evaluated by comparing the simulated leaf area index (LAI), carbon stocks in plant carbon pools, and carbon and water fluxes against observational data. Global-scale simulations forced with GSWP2 data for 1986 to 1995 are performed to answer the question of whether the model, well- constrained against the local observations over the limited number of years, extrapolates well to global scales and captures interannual variation.
