energy_irradiance: Calculate (energy) irradiance from spectral irradiance

Description

This function gives the energy irradiance for a given waveband of a radiation spectrum, optionally applies a BSWF.

Usage

energy_irradiance(w.length, s.irrad, w.band = NULL, unit.in = "energy",
  check.spectrum = TRUE, use.cached.mult = FALSE,
  use.hinges = getOption("photobiology.use.hinges", default = NULL))

Arguments

w.length

numeric array of wavelength (nm)

s.irrad

numeric array of spectral irradiances, by default as energy (W m-2 nm-1)

w.band

waveband

unit.in

a character Allowed values "photon" or "energy", default is "energy"

check.spectrum

logical Flag indicating whether to sanity check input data, default is TRUE

use.cached.mult

logical Flag indicating whether multiplier values should be cached between calls

use.hinges

logical Flag indicating whether to use hinges to reduce interpolation errors

Value

• A single numeric value with no change in scale factor: [W m-2 nm-1] -> [W m-2]
