AB: The land surface models used with climate models have evolved greatly since their inception as hydrometeorological models of surface energy fluxes, momentum transfer, and the hydrologic cycle. Many now include the carbon cycle and dynamic vegetation, in which changes in vegetation structure, function, and biogeography as a result of climate change feed back to affect climate. The evolution of land surface models to include dynamic vegetation has greatly altered our understanding of the role of vegetation in the climate system. Through natural and human-mediated changes in land cover and ecosystem functions, vegetation exerts a strong influence on regional and global climate. Here, the historical development of land surface models is reviewed, as well as the next generation of models and their application to understand climate-vegetation interactions.
