TLDR
In this paper, a bare-soil surface resistance parameter was used to improve the fit of a numerical model of heat and moisture flow in soils to 3 days of field measurements.Abstract:
A bare-soil surface resistance parameter significantly improved the fit of a numerical model of heat and moisture flow in soils to 3 days of field measurements. The resistance removed a positive bias from the model estimates of daily cumulative evaporation on days with minimum surface soil moistureread more

Modeling of land surface evaporation by four schemes and comparison with FIFE observations
Fei Chen,Kenneth E. Mitchell,John Schaake,Yongkang Xue,Hua-Lu Pan,Victor Koren,Qingyun Duan,Michael Ek,Alan K. Betts +8 more
TL;DR: In this article, the authors tested four land surface parameterization schemes against long-term (5 months) area-averaged observations over the 15 km × 15 km First International Satellite Land Surface Climatology Project (ISLSCP) Field Experiment (FIFE) area.

Amazonian Deforestation and Regional Climate Change
TL;DR: The authors used a coupled numerical model of the global atmosphere and biosphere (Center for Ocean-Land- Atmosphere GCM) to assess the effects of Amazonian deforestation on the regional and global climate, and found that when the Amazonian tropical forests were replaced by degraded grass (pasture) in the model, there was a significant increase in the mean surface temperature (about 2.5°C) and a decrease in the annual evapo-transpiration (30% reduction), precipitation (25% reduction) and runoff (20% reduction).

Numerical Analysis of Coupled Water, Vapor, and Heat Transport in the Vadose Zone
TL;DR: In this article, the authors developed a numerical model in the HYDRUS-1D code that solves the coupled equations governing liquid water, water vapor, and heat transport, together with the surface water and energy balance, and provides flexibility in accommodating various types of meteorological information to solve the surface energy balance.
