Image

CO2 frost (10-100 µm) produced by adiabatic expansion of gas is mixed with variable amounts of fine-grained water ice particles (spherical, type SPIPA-A, 4.5 µm average diameter) and the reflectance measured. The reflectance spectra are averaged over Regions Of Interest (ROIs, colored rectangles).
