Describe input parameters grid: RasterModelGrid

A grid.

Blive_init: float, optional
Initial value for vegetation__live_biomass. Converted to field.

Bdead_init: float, optional
Initial value for vegetation__dead_biomass. Coverted to field.

ETthreshold_up: float, optional
Potential Evapotranspiration (PET) threshold for growing season (mm/d).

ETthreshold_down: float, optional
PET threshold for dormant season (mm/d).

Tdmax: float, optional
Constant for dead biomass loss adjustment (mm/d).

w: float, optional
Conversion factor of CO2 to dry biomass (Kg DM/Kg CO2).

WUE: float, optional
Water Use Efficiency - ratio of water used in plant water lost by the plant through transpiration (KgCO2Kg-1H2O).

LAI_max: float, optional
Maximum leaf area index (m2/m2).

cb: float, optional
Specific leaf area for green/live biomass (m2 leaf g-1 DM).

cd: float, optional
Specific leaf area for dead biomass (m2 leaf g-1 DM).

ksg: float, optional
