Abstract

Highly accurate absorption cross-sections, k (cm1atm1), have been measured in the 7.8 ,m band of CFC- 14 (CF4) at temperatures between 180 and 296 K using a high-resolution Fourier-transform spectrometer. The measured absorption cross-sections are free from instrumental distortion, since the spectra were recorded at spectral resolution that was sufficiently high at broadening pressures corresponding to tropospheric and stratospheric layers. Our data were obtained at pressures and temperatures which characterize commonly adapted model atmospheres and represent tangent heights in solar occultation type remote sensing observations of the atmosphere, have also been extended to conditions to be encountered in the atmosphere at Arctic and Antarctic latitudes. The combined absolute intensity of the bands contributing to the absorption around 7.8 m is 1.926 0.012 x 1016 cm molecule .
