The land surface model of the Chinese Academy of Sciences (CAS-LSM),
which includes lateral flow, water use, nitrogen discharge and river
transport, soil freeze thaw front dynamics, and urban planning, was
implemented into the Flexible Global Ocean-Atmosphere-Land System model
grid-point version 3 (CAS-FGOALS-g3). Simulations conducted using the
updated model showed reasonable distributions in the land surface
variables when compared against observations. The new capabilities of
the model with the implementation of the CAS-LSM were also assessed. The
results suggest that the model is a potentially useful tool for studying
the effects of land-surface processes on the global climate, especially
those influenced by human interventions.
