Soil parameters (STAS)

Table 1. NOAH soil parameters

Some of them are shown in Table 2 in Chen and Dudhia 2001. The following is the description of each parameter.

  • BB:SOIL TYPE "B" PARAMETER| used to calculate thermal conductivity of soil (eq. 3 in Chen and Dudhia 2001) and several other quantities
  • DRYSMC: dry soil moisture threshold where direct evap from top soil layer ends (m3/m3)
  • F11: Soil thermal diffusivity/conductivity coef.
  • MAXSMC: Maximum soil moisture (=porosity| m3/m3)
  • REFSMC: Field capacity (equilibrium soil moisture) (m3/m3)
  • SATPSI: Saturation soil suction (m)
  • SATDK : Saturation soil heat conductivity (W/m/K)
  • SATDW : Saturation soil water diffusivity (m/s)

*those for urban are added by K. Sakaguchi from the module_sf_noahlsm.F lines 432~
