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 Senescence coefficient of green/live biomass (d-1). kdd: float, optional Decay coefficient of aboveground dead biomass (d-1). kws: float, optional Maximum drought induced foliage loss rate (d-1). method: str Method name. Tr: float, optional Storm duration (hours). Tb: float, optional Inter-storm duration (hours). PETthreshold_switch: int, optional Flag to indiate the PET threshold. This controls whether the threshold is for growth (1) or dormancy (any other value).
