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 ; skos:exactMatch ; skos:prefLabel "omnidirectional photosynthetic spherical irradiance in sea water"@en ; ns2:hadPrimarySource .
