Description
Particulate CO2 ice produced by crushing a piece of compact CO2 ice and sieving the powder to the 400-800 µm range is mixed with variable amounts of fine-grained water ice (type SPIPA-A, 4.5 µm average) and the reflectance measured. Vis multispectral + NIR low resolution and Vis-NIR high resolution spectra.
