GLASS Structure

The structure of GLASS (see the diagram below) highlights the spatial scales at which the schemes are applied and the degree of interaction allowed with the atmosphere. Four actions will coordinate intercomparisons in land-surface scheme applications. GLASS includes one transversal action, the Assistance for Land-surface Modelling Activities (ALMA), which provides infrastructure and technical support for the intercomparisons. PILPS continues to address local scales and off-line simulations. GLASS also serves as an interface between the land-surface community (e.g, Land-Use and Climate, Identification of robust impacts – LUCID; Project for Intercomparison of Land Data Assimilation Systems – PILDAS) and other GEWEX projects (e.g, LandFlux).
