| emissivity |
The intrinsic strength of an atomic transition that produces a spectral line. The term encapsulates all the atomic data information needed to calculate the flux. It is often generalized to also refer to continuum processes. Units are usually [10 -23 ergs cm 3 s -1 ]. Sometimes also presented as [ph cm 3 s -1 ], and especially for continuum emissivities, [(erg|ph) cm 3 s -1 ?-1 ]

| emissivity |
also called emittance - the non-dimensional ratio of the radiance emitted from an object at a particular wavelength to the radiance that a blackbody would emit at that same temperature and wavelength. Thus a surface with an emissivity equal to 1.0 is a blackbody. All natural surfaces have emissivities less than 1.0, although most earth land surfaces have infrared emissivities between 0.9 and 1.0.
