Modeling of heat-, water-, and carbon-exchange processes in a pine forest ecosystem

A block of carbon exchange in a boreal forest ecosystem is developed. This block is incorporated into the SWAP physically based model previously developed by the authors and describing the heat and water exchange of the land surface with the surface air layer. This has made it possible to use a new version of the model SWAP-Q for modeling the secular dynamics of carbon budget in a pine forest ecosystem. The modeled values of the net radiation of the land surface, turbulent fluxes of latent and sensible heat, and carbon budget are compared to the data of observations at the Lubos experimental site (Netherlands) included into the CarboEuroFlux international network of observations of carbon budget dynamics in terrestrial ecosystems.
