®8.1.12 Lower Boundary:
- Option 1 -
Specified surface temperature and moisture function or specified surface fluxes coupled with constant flux layer condition based on similarity theory (Manton and Cotton, 1977)
-
Option 2 -
Surface layer temperature and moisture fluxes are diagnosed as a function of the ground surface temperature derived from a surface energy balance (Mahrer and Pielke, 1977). The energy balance includes longwave and shortwave radiative fluxes, latent and sensible heat fluxes, and conduction from below the surface. To include the latter effect, a multi-level prognostic soil temperature model is computed.
-
Option 3 -
Modified form of Option 2 with prognostic surface equations (Tremback and Kessler, 1985)
-
Option 4 -
Same as Option 2, except vegetation parameterizations are included (McCumber and Pielke, 1981; McCumber, 1980) (To be implemented)
