Coupling of the CAS‐LSM Land‐Surface Model With the CAS‐FGOALS‐g3 Climate System Model
Abstract 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 in the Flexible Global Ocean‐Atmosphere‐Land System model, grid‐point ver...
