CDSD-296 (Carbon Dioxide Spectroscopic Databank): Updated and Enlarged Version for Atmospheric Applications

We present the current version of the CDSD databank1 aimed at atmospheric applications. The databank contains line parameters (positions, intensities as well as HITRAN air- and self-broadened halfwidths and coefficients of temperature dependence of airbroadened halfwidths) of eight most abundant isotopic species of CO2. The reference temperature is 296 K, the intensity cutoff is 10-30 cm_1/(molecule cm_2 ) and the spectral range is 405-12784 cm_1 . The databank was generated within the framework of the method of effective operators and based on global fittings of parameters of the effective operator models to observed data collected from the literature. Detailed comparisons with HITRAN and a recent CO2 databank by Toth2 will also be given.
