Comments: The CO2 extinction coefficient in the 1700–3000 Å region has been measured. The results show 
excellent agreement with other recent observations to a long-wavelength limit of about 1950 Å. At longer 
wavelengths the present results indicate considerably lower cross sections; the extinction cross section is 
dominated by Rayleigh scattering in the region longward of 2035 Å
