Summary

Abstract: The Community Land Model is the land model for the Community Climate System Model (CCSM) and the Community Atmosphere Model (CAM). It is a collaborative project between scientists in the Terrestrial Sciences Section of the Climate and Global Dynamics Division (CGD) at the National Center for Atmospheric Research (NCAR) and the CCSM Land Model Working Group. Other principal working groups that also contribute to the CLM are Biogeochemistry, Paleoclimate, and Climate Change and Assessment. The model formalizes and quantifies concepts of ecological climatology. Ecological climatology is an interdisciplinary framework to understand how natural and human changes in vegetation affect climate. It examines the physical, chemical, and biological processes by which terrestrial ecosystems affect and are affected by climate across a variety of spatial and temporal scales. The central theme is that terrestrial ecosystems, through their cycling of energy, water, chemical elements, and trace gases, are important determinants of climate. The model has several components: - Biogeophysics - Hydrologic cycle - Biogeochemistry - Dynamic vegetation http://www.cgd.ucar.edu/tss/clm/
