skos:definition "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. Omnidirectional spherical irradiance is the radiation incident on unit area of a spherical (or 4-pi) collector. It is sometimes called scalar irradiance. Radiation incident on a 2-pi collector has standard names of spherical irradiance which specify up/downwelling."@en ;
