Vertical profiles

Description

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

Usage

vprofile_leafAreaDensity(
  x,
  SpParams = NULL,
  z = NULL,
  gdd = NA,
  byCohorts = FALSE,
  bySpecies = FALSE,
  includeHerbs = FALSE,
  draw = TRUE,
  xlim = NULL
)

vprofile_rootDistribution(
  x,
  SpParams,
  d = NULL,
  bySpecies = FALSE,
  draw = TRUE,
  xlim = NULL
)

vprofile_fuelBulkDensity(
  x,
  SpParams,
  z = NULL,
  gdd = NA,
  draw = TRUE,
  xlim = NULL
)

vprofile_PARExtinction(
  x,
  SpParams,
  z = NULL,
  gdd = NA,
  includeHerbs = FALSE,
  draw = TRUE,
  xlim = c(0, 100)
)

vprofile_SWRExtinction(
  x,
  SpParams,
  z = NULL,
  gdd = NA,
  includeHerbs = FALSE,
  draw = TRUE,
  xlim = c(0, 100)
)

vprofile_windExtinction(
  x,
  SpParams,
  u = 1,
  windMeasurementHeight = 200,
  boundaryLayerSize = 2000,
  target = "windspeed",
  z = NULL,
  gdd = NA,
  includeHerbs = FALSE,
  draw = TRUE,
  xlim = NULL
)

Arguments

`x`	An object of class `forest`
`SpParams`	A data frame with species parameters (see `SpParamsMED`).
`z`	A numeric vector with height values.
`gdd`	Growth degree days.
`byCohorts`	Separate profiles for each cohort.
`bySpecies`	Aggregate cohort profiles by species.
`includeHerbs`	Include herbaceous layer in the profile.
`draw`	Logical flag to indicate that a plot is desired.
`xlim`	Limits of the x-axis.
`d`	A numeric vector with soil layer widths.
`u`	The value of measured wind speed (in m/s).
`windMeasurementHeight`	Height corresponding to wind measurement (in cm over the canopy).
`boundaryLayerSize`	Size of the boundary layer (in cm) over the canopy.
`target`	Wind property to draw, either "windspeed", "kineticenergy" (turbulent kinetic energy) or "stress" (Reynold's stress).

Value

If draw = FALSE, the functions return 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.

If draw = TRUE the functions return a ggplot object, instead.
