These parameters are functions of land-use category. Fields identified as "background" may be modified by snow-cover effects. The "background" value does not include snow-cover effects.
SHDFAC:Green vegetation fraction [fraction 0.0 to 1.0]
NROOT:Rooting depth [soil layer index]
RS:Stomatal resistance [s m-1]
RGL:Parameter used in radiation stress function [units? Looks like a dimensionless multiplication factor to me]
HS:Parameter used in vapor pressure deficit function [units?? Looks like a dimensionless multiplication factor to me]
SNUP:Threshold water-equivalent snow depth [m] that implies 100% snow cover
MAXALB:Upper bound on maximum albedo over deep snow [%]
LAIMIN:Minimum leaf area index through the year [dimensionless]
LAIMAX:Maximum leaf area index through the year [dimensionless]
EMISSMIN:Minimum background emissivity through the year [fraction 0.0 to 1.0]
EMISSMAX:Maximum background emissivity through the year [fraction 0.0 to 1.0]
ALBEDOMIN:Minimum background albedo through the year [fraction 0.0 to 1.0]
ALBEDOMAX:Maximum background albedo through the year [fraction 0.0 to 1.0]
Z0MIN:Minimum background roughness length through the year [m]
Z0MAX:Maximum background roughness length through the year [m]
Several additional parameters in VEGPARM.TBL are not functions of land-use category:
TOPT_DATA:Optimum transpiration air temperature [K]
CMCMAX_DATA:Maximum canopy water capacity [volumetric fraction]
CFACTR_DATA:Parameter used in the canopy interception calculation [dimensionless]
RSMAX_DATA:Maximal stomatal resistance [s m-1]
BARE:The land-use category representing bare ground (used to set the vegetation fraction to zero) [land-use category index]
NATURAL:The land-use category representative of the non-urban portion of urban land-use points [land-use category index]
