Abstract

Land surface models simulate the temporal evolution of the energy and water balance at and near the land surface. These models can be used coupled to an atmospheric model, in which case feedbacks between the land surface and atmosphere are explicitly represented, or they can be used in a stand-alone, uncoupled mode, in which case observed or simulated atmospheric conditions act as time-varying boundary conditions. This article reviews the basic layout of land surface models, their history, and their uses, specifically in uncoupled simulations. In this context, the challenges of model performance evaluation and the role of model intercomparison projects are discussed. The article ends with a look toward the future and the next series of developments that land surface models are likely to undergo.
