"toa" means top of atmosphere. "Photon radiance" is the photon flux in a particular direction, per unit of solid angle. The direction is specified as "outgoing", i.e. radiation from below. A photon flux is specified in terms of numbers of photons expressed in moles. The "per unit wavelength" indicates a spectrally resolved quantity. A coordinate variable for radiation wavelength should be given the standard name radiation_wavelength.
