Databases of Laboratory Measurements A database maintained by a Brazilian group that contains optical constants of different type of ices: pure, mixed and energetically processed by cosmic ray analogues in the laboratory. - SubLIME, Sublimation Laboratory Ice Millimeter/submillimeter Experiments - The lab measurements in UV - mid-IR range for rocks and minerals. - cosmic Ices Lab (NASA) 

Solid Spectroscopy Hosting Architecture of Databases and Expertise | SSHADE - visible-6 microns and also Raman, with the sample enclosed within a cell, so can explore solid, liquid, vapor phase equilibrium, for temperatures down to 30 K and pressures up to ~3 bar. The samples are thick, usually 5 or 20 mm that give a good sensitivity for the very weak near-IR features in transmission, but limited ability to study stronger absorptions. More limited vapor-deposited thin film capability down to 7 K and out to about 20 microns. - Reference & DataBase of Optical Constants - Stony Brook University Vibrational Spectroscopy Laboratory; working to determine the optical constants (n and k) of many minerals at various orientations. For uniaxial minerals, determine n and k for the O and E rays. For other minerals, determine the three principal complex refractive indices. Determine n and k by acquiring mid-IR emissivity or reflectance spectra and applying dispersion theory to generate optical constants that provide best-fit models to the measured spectra. - Heidelberg - Jena - St.Petersburg - Database of Optical Constants (HJPDOC) - Granada-Amsterdam Light-Scattering Database; light scattering measurements of particles (scattering matrix, angular and wavelength dependence). - RELAB; KECK/NASA REFLECTANCE EXPERIMENT LABORATORY. Spectroscopic data acquired in the laboratory provide the interpretive foundation upon which compositional information about unexplored or unsampled planetary surfaces is derived from remotely obtained reflectance spectra.


Light-Scattering Codes a link to the repository for published optical constants codes. and resources/tamudust2020 database for optical properties of dust aerosol and volcanic ash particles. Various ensembles of 20 irregular hexahedral particle models are applied in this database. - the 'SIRIS' code for single particles (with internal diffuse scatterers) and the MC RT code 'RT-CB' codes. -T-matrix codes for non-spherical particles database of various computer codes for inhomogeneous particles - various codes for the computation of (polarized) bidirectional reflectance of flat particulate layers and rough surfaces the T-matrix superposition code for aggregates (MSTM) - the DDA collection of codes by B. Draine and P, Flatau (can be used for any type and structure of particles) - an extensive database of the codes for light scattering by particles by T. Wriedt - a library of the DDA codes by P. Flatau - this collection was developed for medical imaging applications, but the codes + accompanying references are useful for learning about (and potentially teaching). - Planetary Spectrum Generator (PSG) for atmospheres and surfaces
