Abstract (Brief description of the experiment contents (initial conditions, boundary conditions, etc.))
For better simulating greenhouse gas fluxes, the CO2 and CH4 fluxes by the process-based model, VISIT, were optimized using observed data at a black spruce forest in Fairbanks, AK. The model was modified for better simulating soil temperature and water table depth by coupled the heat conduction model and the tank model, respectively. The model was driven using CRUNCEP climate data, and the modeled fluxes was optimized with a differential evolution method.
