Spectral absorption of solid CO2 from the ultraviolet to the far-infrared

Solid CO2 is known to be abundant in the seasonal polar caps of Mars and occurs in lesser amounts in several icy bodies in the outer solar system. The measurements presented here were undertaken to obtain accurate absorption coefficients for solid CO2 at all weakly absorbing wavelengths between the ultraviolet and far-infrared. The measurements were made by transmission spectroscopy on mm- to cm-thick clear ice samples grown by a technique similar to that of Gaizauskas (1955). (AIAA)
