This file contains a single namelist called JULES_RED that sets parameters relevant to the Robust Ecosystem Demography submodel (RED version 1.0) <https://gmd.copernicus.org/articles/13/4067/2020/>`_.
Activate RED in the :nml:mem:`JULES_VEGETATION::l_red.
JULES_RED namelist members¶
This namelist is used to read PFT parameters that are only needed by the Robust Ecosystem Demography (RED). Values are not used if RED is not selected.
Note
Where a quantity is said to have units of “/360days”, this means that it is an amount per 360 days.
- RED_PARMS::alpha_recrt¶
- Type:
real(npft)
- Default:
None
The fraction of PFT carbon assimilate devoted to reproduction.
- RED_PARMS::crwn_area0¶
- Type:
real(npft)
- Default:
None
The lowest PFT crown area, value corresponds to the mass0 class (m2).
- RED_PARMS::dom_order¶
- Type:
integer(npft)
- Default:
None
The value that describes the competitive hierarchy of PFTs competition in JULES-RED, the higher the value the more dominant: 3 (trees), 2 (shrubs), 1 (grass).
- RED_PARMS::height0¶
- Type:
real(npft)
- Default:
None
The lowest PFT height, value corresponds to the mass0 class (m).
- RED_PARMS::lai_bal0¶
- Type:
real(npft)
- Default:
None
The lowest PFT balanced LAI, which corresponds to the mass0 class (m2/m2).
- RED_PARMS::mass0¶
- Type:
real(npft)
- Default:
None
The lowest PFT mass class (kg C).
- RED_PARMS::massi¶
- Type:
real(npft)
- Default:
None
The highest PFT mass class (kg C).
- RED_PARMS::mclass¶
- Type:
integer(npft)
- Default:
None
Number of mass classes for each PFT.
- RED_PARMS::mort_base¶
- Type:
real(npft)
- Default:
None
The baseline PFT mortality rate (/360 days).
- RED_PARMS::phi_a¶
- Type:
real(npft)
- Default:
0.50

- RED_PARMS::phi_g¶
- Type:
real(npft)
- Default:
0.75
The allometric/power scaling of PFT mass to PFT mass growth rate (West, G. B., et al., 1997 <https://www.science.org/doi/10.1126/science.276.5309.122>`_).
- RED_PARMS::phi_h¶
- Type:
real(npft)
- Default:
0.25
The allometric/power scaling of PFT mass to PFT height (Niklas, K. J., et al., 2001 <https://doi.org/10.1073/pnas.041590298>`_).
- RED_PARMS::phi_l¶
- Type:
real(npft)
- Default:
0.25
