Description
Converts radiation from W m-2 to µmol m-2 s-1 and vice versa.
Usage
1
2
convert_radiation(x, frac_ppfd = 0.5, calc_frac = FALSE,
method = c("to_rg", "to_ppfd"))
Arguments
frac_ppfd
Fraction of incoming solar irradiance that is
photosynthetically active radiation (ppfd); defaults to 0.5.
Rg
Global radiation = incoming short-wave radiation at the surface
(in units W m-2).
PPFD
Photosynthetic photon flux density (µmol m-2 s-1).
J_to_mol
Conversion factor from J m-2 s-1 (= W m-2) to µmol m-2 s-1.
Details
The conversion is given by:
ppfd = rg * frac_ppfd * J_to_mol
by default, combined conversion factor (frac_ppfd * J_to_mol) is 2.3
