GEISA sub-database on Atmospheric Aerosols
|
General presentation
As satellite and other remote sensing measurements become more demanding in terms of the accuracy of gas species retrievals, knowledge of the optical properties of aerosols (e.g. aerosol extinction and absorption coefficients, single scattering albedo, asymmetry parameter) also becomes increasingly important, since total optical depths are dependent upon both gases and aerosols in a planetary atmosphere.
Consequently, is included, since the 2003 edition of GEISA [1], a sub-database containing microphysical and optical properties of atmospheric aerosols, hereafter GEISA-2015/Aerosols which gathers the micro-physical and optical properties of atmospheric aerosols and complementary information on other public aerosols dedicated databases.
The aerosol data of the GEISA-2015 edition [2] are available from two series of catalogs. A significant update has been made thanks to the implementation of complementary data of two origins: from Massie [3] at NCAR and from the ARIA archive developed at Oxford University.
Database Access : The main GEISA-2015/Aerosols database on refractive indices of basic atmospheric aerosol components
A summarized description contents is given below:
Two public databases already available since GEISA-2003 edition:
- The aerosols database from LITMS [5]
- The database and associated software package OPAC (Optical Properties of Aerosols and Clouds) by Hess et al. 1998 [6]
