skos:definition "Downwelling radiation is radiation from above. It does not mean net downward. 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. Photon spherical irradiance is the photon flux incident on unit area of a hemispherical (or 2-pi) collector. The direction (up/downwelling) is specified. Radiation incident on a 4-pi collector has a standard name referring to omnidirectional spherical irradiance. A photon flux is specified in terms of numbers of photons expressed in moles."@en ;
