Fluorescence
From Glossary of Meteorology
fluorescence
The emission of radiation associated with the relaxation of an atom or molecule from an excited energy level to a lower (usually ground state) level.
The emission can be in the visible or ultraviolet if an electronic transition is involved, or in the infrared if it is a vibrational transition.
