HITRAN
Encyclopedia
HITRAN - HITRAN is a compilation of spectroscopic parameters that a variety of computer codes use to predict and simulate the transmission
and emission of light in the atmosphere. The original version was compiled by the Air Force Cambridge Research Laboratories (1960's). It is maintained and developed at the Harvard-Smithsonian Center for Astrophysics, Cambridge MA, USA.
HITRAN is the worldwide standard for calculating or simulating atmospheric molecular transmission and radiance from the microwave through ultraviolet region of the spectrum. The current version contains 42 molecular species along with their most significant isotopologues. These data are archived as a multitude of high-resolution line transitions. There are in addition many molecular species collected as cross-section data. These latter include anthropogenic introduced constituents in the atmosphere such as the chlorofluorocarbons.
Transmittance
In optics and spectroscopy, transmittance is the fraction of incident light at a specified wavelength that passes through a sample. A related term is absorptance, or absorption factor, which is the fraction of radiation absorbed by a sample at a specified wavelength...
