energy_irradiance: Calculate (energy) irradiance from spectral irradiance

In photobiology: Photobiological Calculations

Calculate (energy) irradiance from spectral irradiance

Description

Energy irradiance for a waveband from a radiation spectrum, optionally applying a "biological spectral weighting function" or 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 vector of wavelength [nm].
s.irrad	numeric vector of spectral irradiances in [W\,m^{-2}\,nm^{-1}] or [mol\,s^{-1}\,sm^{-2}\,nm^{-1}] as indicated by the argument pased to unit.in.
w.band	waveband.
unit.in	character Allowed values "energy", and "photon", or its alias "quantum".
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 insert "hinges" into the spectral data before integration so as to reduce interpolation errors at the boundaries of the wavebands.

Value

A single numeric value with no change in scale factor: [W\,m^{-2}].
