Besides the molecular species which define the gaseous infrared opacity in the Earths
atmosphere aerosol particles also contribute to this opacity.
Consequently, a common GEISA and GEISA/IASI aerosols sub-database, has been elaborated.
It gathers the micro-physical and
optical properties from four published aerosol data catalogs, i.e. : Massie (1994, 2003, 2004),
Rublev (1994) ,
Koepke (1997), the overall content of which deals with the
archive of complex refractive indices and possibly computed optical related properties, for
selected basic aerosol components.
Softwares for data management and user-selected aerosol mixtures elaboration are available as well.
