Information

This model computes the evaporation of the soil. It uses the generic evaporation model together with an internal modulation computing the conductance of evaporation. 

Parameters:

  ag:      Ground area of Biosphere (default value = 2368.9 m2)

  hai:     Convection coefficient equation intercept (default value = 39.6 kJ/(h.m2.K))

  apix:    Portion of Biosphere covered by pond (default value = 0.4)

  lambda:  Latent heat of vaporization (default value = 2501 kJ/kg_water)

  rg:      Specific ground resistance of evaporation to vapor diffusion (default value = 0.0278 h.m2/kg_air)

  pao:     Atmospheric pressure (default value = 87.848 kPa)
