DLI
Daily Light Integral is the total number of photosynthetically active photons that impinge upon 1 m2 surface area over a 24 hour period. A good way to think of DLI is the total amount of radiation that is available for plant growth in a given day.
PPFD
The photosynthetic photon flux density (PPFD) is measured by the QSO-S PAR Photon Flux sensor in units of μmol m-2 s-1. This instantaneous value is averaged over the measurement interval by the data logger.
DLI (μmol m-2) = ∑(total mols per square meter in a 24 hour period)
DLI is typically reported in mols m-2.
DLI mols m-2= DLI ((μmol m-2) / 1,000,000
