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] |
