CLM

Community Land Model

The Community Land Model (CLM) is the land component of the Community Climate System Model .

It is a collaborative project between scientists in the Terrestrial Sciences Section (TSS) and the Climate and Global Dynamics Division (CGD) at the National Center for Atmospheric Research (NCAR) and the CESM Land Model Working Group.

The model formalizes and quantifies concepts of ecological climatology. Biophysical processes simulated by CLM include solar and longwave radiation interactions with vegetation canopy and soil, momentum and turbulent fluxes from canopy and soil, heat transfer in soil and snow, hydrology of canopy, soil, and snow, and stomatal physiology and photosynthesis. Vegetation cover in CLM is represented by several plant functional types (PFTs) which differ in their ecological and hydrological characteristics. Texture types determine thermal and hydrologic properties of soil.
