Arguments
- watts
PAR (W / m2)
Value
PPFD (umol / m2 / s)
Details
Converts photosynthetically active radiation (PAR, units of Watts / m2) to
photosynthetic photon flux density (PPFD) in units of umol / m2 / s
From Campbell and Norman p151
PPFD = PAR * (J/m2/s) * (1 mol / 2.35e5 J)
2.35e5 J / mol is the energy content of solar radiation in the PAR waveband
