grow: LINKAGES growth function

In araiho/linkages_package: A Linked Forest Productivity - Soil Process Model

Description

GROW CALCULATES DIAMETER GROWTH FOR EACH TREE BY DECREASING MAXIMAL GROWTH TO THE EXTENT THAT THE MOST LIMITING RESOURCE IS LESS THAN OPTIMAL.

Usage

grow(max.ind, nspec, ntrees, frt, slta, sltb, dbh, fwt, b2, b3, itol, g, degdgf,
  smgf, sngf, frost, rt, iage, nogro)

Arguments

max.ind	maximum number of individuals
nspec	number of species
ntrees	number of trees of each species
frt	foliage retention time
slta	parameter to calculate crown area from diameter
sltb	parameter to calculate crown area from diameter
dbh	diameter of each tree
fwt	leaf weight per unit crown area
b2	growth scaling parameter
b3	growth scaling parameter
itol	shade tolerance code for each species
g	scalar for species maximum diameter increment
degdgf	growing degree day growth factor from gmult.R
smgf	soil moisture growth factor from gmult.R
sngf	soil nitrogen growth factor from gmult.R
frost	minimum January temperature tolerated
rt	current monthly temperature
iage	age of each individual
nogro	flags slow growing individuals

Value

dbh diameter of each individual

ntrees number of trees of each species

awp aboveground woody production
