Biogeophysics refers to the instantaneous exchanges of energy, water, and momentum with the atmosphere. It concerns aspects of micrometeorology, canopy physiology, soil physics, radiative transfer, and hydrology. Dust emissions and aerosol deposition onto snow are also represented in the model.
The Community Earth System Model (CESM) is a fully-coupled, global climate model that provides state-of-the-art computer simulations of the Earth's past, present, and future climate states.
CESM is sponsored by the National Science Foundation (NSF) and the U.S. Department of Energy (DOE). Administration of the CESM is maintained by the Climate and Global Dynamics Laboratory (CGD) at the National Center for Atmospheric Research (NCAR).
