! ------------------------------------------------------------------ ! file 'b1glob.inc' ! This common block contains variables representing the daily ! updated biomass (live and dead) properties for each subregion. ! These variables may be used to estimate other vegetative ! geometric and mass properties. ! ! All of these variables are updated within "main" on a daily ! basis for erosion and outputs. Only a "biomass update" process ! is intended to modify these variables since they are all dependent ! upon the individual live (crop) and dead (residue) biomass values. !
