    Brief introduction to Land surface model

  " It is clear that many ecological, hydrological, and atmospheric processes are so interwined that these cannot be considered separate disciplines. ... Successful modeling of latent and sensible heat fluxes requires an accurate description of the ecological state and biogeochemical controls in addition to the traditional emphasis on the physical environment." - Bonan (1996)

  Land surface model CESAGCM is from NCAR's land model (LSM1.0, Bonan(1996)). The calculation of momentum, heat and moisture fluxes at one grid-point is conducted in each sub-grid (3 vegetation, lake and wet land) and combined with specified weights.
