We have an existing standard name of
  surface_downwelling_photosynthetic_radiative_flux_in_air
and I assume your proposal means the fraction of this which is absorbed by
the vegetation. Is that right? If so, it would be better to add to this
existing name (without in_air, I think) to make the new one.

Best wishes

Jonathan
