Convert spectral energy irradiance [\(W\,m^{-2}\,nm^{-1}\)] into a spectral photon irradiance expressed in number of molds of photons [\(mol\,s^{-1}\,m^{-2}\,nm^{-1}\)].

Usage

as_quantum_mol(w.length, s.e.irrad)

Arguments

w.length

numeric vector of wavelengths (nm).

s.e.irrad

numeric vector of spectral (energy) irradiance values.

Value

a numeric vector of spectral photon irradiances.

Examples

with(sun.data, as_quantum_mol(w.length, s.e.irrad))
