thickgeometry: Generates vegetation thickness profile

In ilyamaclean/microctools: Various worker functions for microclimc package

Generates vegetation thickness profile

Description

thickgeometry is used is to calculate the mean thickness of leaves and woody vegetation such that volume = Plant Area Index * thickness

Usage

thickgeometry(m, mthick, thmax, thmin)

Arguments

m	number of canopy nodes
mthick	mean thickness of vegetation
thmax	mean thickness of lowest portion of canopy
thmin	mean thickness of upper portion of canopy

Value

a vector of thicknesses for each canopy node (m)

Examples

pai <- PAIgeometry(1000, 10, 7, 70)
thick <- thickgeometry(1000,0.4,0.7,0.1)
hgt <- 25
dens <- thick * pai * length(pai) / hgt
z <- c(1:1000) / 40
par(mar=c(5, 5, 2, 2))
plot(z ~ dens, type = "l",  cex.axis = 1.5, cex.lab = 1.5,
    xlab = expression(paste("Volume ",(~m^3 / m^3))),
    ylab = "Height (m)")
