Term: VolumeEmissionRate
Definition:

The volume emission rate, e(r, t, l), is thenumber of photons emitted per unit source volume per second, i.e.photons/(m3 s), as measured along the line of sight between the source pointand the observer. The Volume Emission Rate is in general a function of theline-ofsight distance, r, time, t, and wavelength, l. The Volume EmissionRate is actually not a directly measurable quantity. However, the term hasbeen commonly used in both data product descriptions and researchpublications.
