Noah Land Surface Model: Unified NCEP/NCAR/AFWA scheme with soil temperature and moisture in four layers, fractional snow cover and frozen soil physics.
Heat & moisture fluxes
1
Heat and moisture fluxes from the surface for real-data cases and when a PBL are on.
Soil layers
5
Number of soil layers in land surface model (set before running real.exe).
Cumulus physics calls time
5
Minutes between cumulus physics calls; should be set to 0 when using allcu_physics except Kain-Fritsch (0 = call every time step).
Radiation calls time
30
Minutes between radiation physics calls.
Boundary layer calls time
0
Minutes between boundary-layer physics calls (0=call every time step).
