An experimental facility has been set up to acquire infrared spectra of pure water ices with controlled grain sizes ranging from 80 to 700 µm and temperatures ranging from 80 to 140 K at 0.01 mbar. Forty-seven near IR spectra (1.0–5.0 µm), selected among the total acquired spectra, permit us to determine how spectral characteristics between 1.0 and 1.8 µm depend on both grain size and temperature.

Vis-NIR reflectance spectra of the Udokan basalts altered in cold and arid environment (Siberia). The samples were collected along lava flow. The experiment contains spectra of the surface of the samples.
Chloride molality varying from 0.03 to 10 m; temperature varying from 25 to 450 °C
This database provides access to the data measured in the Laboratory for Outflow Studies of Sublimating Materials (LOSSy) of the University of Bern. In the laboratory, we are preparing and analyzing analogs of planetary or cometary surfaces composed of pure or mixed ices or dust-ice mixtures to study their optical properties and dynamic evolution under simulated conditions. The collected data can be used to predict photometric properties or to interpret observational data of icy-dust planetary...
