The GEISA 2011 spectroscopic database

The development of GEISA (Gestion et Etude des Informations Spectroscopiques Atmosphériques : Management and Study of Spectroscopic Information) was started in 1976 at Laboratoire de Météorologie Dynamique (LMD) in France [Chédin et al. (1982)], and regularly updated [Husson et al. (1992, 1994), Jacquinet-Husson et al. (1999, 2003a, 2003b, 2005, 2008, 2009)]. GEISA is a computer-accessible spectroscopic database, designed to facilitate accurate forward atmospheric radiative transfer calculations using a line-by-line and (atmospheric) layer-by-layer approach.

The current 2011 edition of GEISA (GEISA 2011) is a system comprising three independent sub-databases devoted respectively to:

GEISA 2011 Description	GEISA 2011 Database Access
Line transition parameters	- Interactive access - FTP access - Graphical tool
Absorption cross-sections	- IR - UV_VIS
Microphysical and optical properties of atmospheric aerosols	Aerosols

Supplemental data are also available, they contains partial or complete information about transition parameters of Earth and planetary atmosphere molecules. Those data were not introduced in the current GEISA 2011 on line edition, but could be of interest for the scientist community :

Supplemental Data GEISA 2011
