Abstract

Laboratory experiments show that solid carbon dioxide is an effective trap for ozone at temperatures as high as 156°K. Ultraviolet reflection-absorption spectra of ozone in solid carbon dioxide at 127°K indicate that the ozone observed over the polar cap of Mars may be trapped in solid carbon dioxide.
