Absolute absorption cross section measurements of CO2 in the wavelength region 163-200 nm and the temperature dependence

Laboratory measurements of the absorption cross section of CO2 at the temperatures 195 and 295 K have been made throughout the wavelength region 163-200 nm by using a high resolution grating spectrometer. Cross sections at 195 K are smaller than those at 295 K, and the band structures are more emphasized as expected. In combining with our previous measurements [J. Quant. Spectrosc. Radiat. Transfer, 55 (1996) 53], the absorption cross sections of CO2 are available in the wavelength region 117.8-200.0 nm at 295 K and 117.8-192.5 nm at 195 K
