Please add a class photosynthetic photon flux density
has exact synonym PPFD
definition Number of photons in the 400-700 nm range received by a surface for a specified amount of time;
https://en.wikipedia.org/wiki/Photosynthetically_active_radiation
I don't know under which class to add it. It is not really a density as defined by PATO.

celineaubert changed the title from New classes: photosynthetic photon flux density, photosynthetic photon flux density measurement datum to New class: photosynthetic photon flux density Nov 3, 2016
