SSHADE: \"Solid Spectroscopy Hosting Architecture of Databases and Expertise\"

Bernard Schmitt, Philippe Bollard, Damien Albert, Alexandre Garenne, Maria Gorbacheva, Lydie Bonal, Pierre Volcke & the SSHADE Partner's Consortium and
SSHADE is the database infrastructure and interface that contains and provides access to the experimental and field spectroscopic data of solids of all partner's databases. It is also the central database containing all the common data on the fundamental species (atoms, molecules, chemical functions, chemical bonds), the fondamental phases (minerals, solids, liquids), the objects (meteorites, micrometeorites, IDPs), the planetary bodies, the international matters, and the publications. It also contains a bandlist database of molecular solids...

Optical constants of Mg- and Fe-rich amorphous silicate Mg$_{(1-x)}$Fe$_x$SiO$_3$, x=0.1 - 0.2 - 0.3 - 0.4, 10-300 K, UV-mm range

Karine Demyk
UV to mm optical constants of four Mg- and Fe-rich amorphous silicates Mg$_{(1-x)}$Fe$_x$SiO$_3$, x=0.1 - 0.2 - 0.3 - 0.4, at 10, 100, 200 and 300 K. The optical constants are calculated from mass absorption coefficients measured in the 5 - 1000 µm (2000-10 cm-1) range and extrapolated in the range 0.024 - 5 µm and 1000 - 100000 µm.

Vis-NIR bidirectional reflection spectra of spherical water ice particles for different sizes (2 to 100 µm), temperatures (173 and 223 K) and temporal evolutions

Olivier Poch, Zuriñe Yoldi & Bernhard Jost
Three types of water ice particles were prepared, having three grain size distributions: 4.5±2.5 µm, 67±31 μm, and between 2 and 100 µm. Reflectance spectra (from 0.4 to 4 µm) of 5mm-deep surfaces of these particles were measured at 173 K, and some at 223 K, under primary vacuum. During time, the particles undergo metamorphism (recristallisation/sintering, change of grains shape and size) and spectra were measured again several hours after the measurement of the fresh...
