Land Surface Model CAS-LSM: Model Description and Evaluation
Comprehensive land surface models are very important for climate and weather forecasting and for improving our understanding of the relationships between humans and the Earth system. This work presents a land surface model of the Chinese Academy of Sciences (CAS-LSM) that considers groundwater later...

Comprehensive land surface models are very important for climate and weather forecasting and for improving our understanding of the relationships between humans and the Earth system. This work presents a land surface model of the Chinese Academy of Sciences (CAS-LSM) that considers groundwater lateral flow, human water regulation, soil freeze-thaw front dynamics, riverine dissolved inorganic nitrogen transport, anthropologic heat release, urban water usage, and urban planning based on the Community Land Model. Global simulations with the updated CAS-LSM were conducted to evaluate its performance, and the results show its advantages in reproducing ecohydrological processes. Groundwater lateral flow can replenish the groundwater depletion cone caused by overexploitation, where the offset rate increases as the aquifer thickness increases. The maximum thaw depth increases by 3.62 mm yr(-1) in permafrost areas, and the maximum frost depth decreases by 1.89 mm yr(-1) in seasonally frozen areas. Nitrogen fertilizer use and point-source pollution increase the riverine dissolved inorganic nitrogen flow rate in western Europe and eastern China.
