It does not mean net downward. Radiative flux is the sum of shortwave and longwave radiative fluxes. Photosynthetic radiation is the part of the spectrum which is used in photosynthesis e.g. 400-700 nm. The range of wavelengths could be specified precisely by the bounds of a coordinate of radiation_wavelength.
