The HITRAN Database |
The HITRAN compilation, and its analogous database
HITEMP (high-temperature spectroscopic absorption parameters), are
now being developed at the Atomic and Molecular Physics Division,
Harvard-Smithsonian Center for Astrophysics under the continued
direction of Dr. Laurence S. Rothman.

HITRAN is an acronym for
high-resolution
transmission molecular absorption
database. 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 database
is a long-running project
started by the Air Force Cambridge
Research Laboratories (AFCRL) in
the late 1960's in response to the
need for detailed knowledge of the infrared properties of the
atmosphere.

The current edition of the HITRAN molecular spectroscopic database and
associated compilation (v13.0) is available on an ftp site located at
the Smithsonian Astrophysical Observatory in Cambridge, USA.
Updates and corrections to the compilation will be made available on this
web-site under the sub-page HITRAN UPDATES. |

In addition to the Mega-line HITRAN2008 database, there are directories containing files of aerosol indices of refraction, UV line-by-line and absorption cross-section parameters, and more extensive IR absorption cross-sections. Supplemental folders are used for line-by-line parameters in cases where more complete information may be contained in the corresponding cross-section files, and also where we have archived some cross-sections files that contain information very similar to newer data. |
The HAWKS (HITRAN Atmospheric Workstation) software has been written in the Java language for improved cross-platform compatibility. This software manipulates, filters, and plots the line-by-line data as well as the absorption cross-sections, in Windows, UNIX, and MAC operating systems. |

The database can be downloaded from an internet site. The
instructions for accessing the compilation may be obtained by
researchers using their institutional addresses by completing the HITRAN Request Form. Special questions
should be e-mailed to LRothman@CfA.Harvard.edu

A Special Issue of the Journal of Quantitative Spectroscopy and Radiative Transfer (JQSRT) volume 110, numbers 9-10, June/July 2009 has been published. This Special Issue includes 17 articles describing the data that relate to HITRAN. |
