Descriptive table of parameters
JULES implementation
In JULES, all namelist variables are initialised with a missing data indicator (MDI). The MDI value varies according to the type of the namelist variable.
| Namelist variable | Type | Available values | Default values | Description |
|---|---|---|---|---|
| soilin%desc | character(*) | uninitialised | Description of soil types. | |
| soilin%bch | real(n_soiltypes) | >=0.0 | uninitialised | Parameter \(b\) in Campbell equation for the pore size distribution index (1,2) \( ( - ) \). |
| soilin%silt | real(n_soiltypes) | >=0.0 | uninitialised | Fraction of soil which is silt \( ( - ) \). |
| soilin%clay | real(n_soiltypes) | >=0.0 | uninitialised | Fraction of soil which is clay \( ( - ) \). |
| soilin%sand | real(n_soiltypes) | >=0.0 | uninitialised | Fraction of soil which is sand \( ( - ) \). |
| soilin%swilt | real(n_soiltypes) | >=0.0 | uninitialised | Volume of H2O at wilting \( (m^{3} \cdot m^{-3}) \). |
| soilin%sfc | real(n_soiltypes) | >=0.0 | uninitialised | Volume of H2O at field capacity \( (m^{3} \cdot m^{-3}) \). |
| soilin%ssat | real(n_soiltypes) | >=0.0 | uninitialised | Volume of H2O at saturation \( (m^{3} \cdot m^{-3}) \). |
| soiln%hyds | real(n_soiltypes) | >=0.0 | uninitialised | Hydraulic conductivity at saturation \( (m^{-1}) \). |
| soilin%sucs | real(n_soiltypes) | <=0.0 | uninitialised | Suction at saturation \( (m) \). |
| soilin%rhosoil | real(n_soiltypes) | >=0.0 | uninitialised | Soil bulk density \( (kg \cdot m^{-3}) \). |
| soilin%css | real(n_soiltypes) | >=0.0 | uninitialised | Soil specific heat capacity \( (J \cdot kg^{-1} \cdot K^{-1}) \). |
