We store tables of extinction, scattering, absorption, etc. on our server at the link below. Also includes a collection of aerosol refractive indices. Coming Soon!

Aerosol refractive index databases that include atmospheric aerosol species. These databases are not part of MIRA, but we provide them here as a service. Please be sure to acknowledge these sources appropriately. 
The Earth Observation Data Group in the Deprtment of Physics at the University of Oxford has a very nice database with hundreds of aerosol refractive indices; includes nice graphics and ascii downloads. Infrared refractive indices for many minerals, include iron oxides; downloadable ascii: Cosmic dust database, but includes some iron oxides: HITRAN California Institute of Technology Mineral Spectroscopy Server includes many mineral spectra and links to other databases:
