The 2003 edition of the GEISA/IASI spectroscopic database

Abstract: The content of the current (2003) version, GEISA/IASI-03, of the computer-accessible spectroscopic database, GEISA/IASI, is described. This “system” or database is comprised of three independent spectroscopic archives, which are (a) a database of individual spectral line parameters on 14 molecules, , , , , CO, , , NO, , , , OCS, , , and the related 51 isotopomers and isotopologues, representing 702,550 entries, in the spectral range 599–, (b) a database of spectral absorption cross-sections(6,572,329 entries related to six molecules, CFC-11, CFC-12, CFC-14, HCFC-22, , ), and a catalogue of microphysical and optical properties (mainly, the refractive indices) of atmospheric aerosols. The modifications and improvements, which have been implemented since the earlier editions of this database, in terms of content and management, have been explained in detail. GEISA/IASI has been created with the specific purpose of assessing the capability of measurement by the IASI instrument within the designated goals of ISSWG in the frame of the CNES/EUMETSAT European Polar System preparation. All the archived data can be handled through a user-friendly associated management software, which is posted on the ARA/LMD group web site at http://ara.lmd.polytechnique.fr. [Copyright &y& Elsevier]
