GEISA : spectroscopic database

spectroscopic database

The project

Since over three decades, the ARA (Atmospheric Radiation Analysis) group at LMD (Laboratoire de Météorologie Dynamique, France) has developed GEISA (Gestion et Etude des Informations Spectroscopiques Atmosphériques: Management and Study of Atmospheric Spectroscopic Information), a computer accessible database system [Chédin et al. (1982), Husson et al. (1992), Jacquinet-Husson et al. (1999, 2005, 2008, 2011, 2016), Armante et al (2016), designed to facilitate accurate and fast forward, calculations of atmospheric radiative transfer using a line-by-line and (atmospheric) layer-by-layer approach. This effort has proven to be beneficial to the atmospheric scientific community participating in direct and inverse radiative transfer studies.

Products available
