Vertical profiles: Vertical profiles

Description

Functions to generate vertical profiles generated by an input forest object.

Usage

vprofile.LeafAreaDensity(x, SpParams, z = NULL, gdd = NA, 
                         byCohorts = FALSE, bySpecies = FALSE, draw = TRUE, 
                         legend = TRUE, xlim = NULL)
vprofile.RootDistribution(x, SpParams, d = NULL,  bySpecies = FALSE, draw = TRUE, 
                          legend = TRUE, xlim = NULL)
vprofile.FuelBulkDensity(x, SpParams, z = NULL, gdd = NA, draw = TRUE)
vprofile.PARExtinction(x, SpParams, z = NULL, gdd = NA, draw = TRUE)
vprofile.SWRExtinction(x, SpParams, z = NULL, gdd = NA, draw = TRUE)
vprofile.WindExtinction(x, SpParams, wind20H, z = NULL,  gdd = NA, draw = TRUE)

Arguments

x

An object of class forest

SpParams

A data frame with species parameters (see SpParamsMED).

z

A numeric vector with height values.

d

A numeric vector with soil layer widths.

gdd

Growth degree days.

byCohorts

Separate profiles for each cohort.

bySpecies

Aggregate cohort profiles by species.

wind20H

The value of measured wind speed at 6 m = 20ft (in m/s).

draw

Logical flag to indicate that a plot is desired.

legend

Logical flag to indicate that legend should be included.

xlim

Limits of the x-axis.

Value

A numeric vector with values measured at each height. Units depend on the profile function:

• vprofile.LeafAreaDensity: Cumulative LAI (m2/m2) per height bin.

• vprofile.FuelBulkDensity: Fuel bulk density (kg/m3) per height bin.

• vprofile.PARExtinction: Percent of photosynthetically active radiation (%) corresponding to each height.

• vprofile.SWRExtinction: Percent of shortwave radiation (%) corresponding to each height.

• vprofile.WindExtinction: Wind speed (m/s) corresponding to each height.
