In 2015 we published an atmospheric version, CDSD-296, of the carbon dioxide spectroscopic databank (CDSD) [Tashkun et al., JQSRT 152 (2015) 45–73]. Since that time many new experimental data have been published. Some CDSD data deficiencies have also been found. The purpose of the present work is to present a corrected and extended version of the databank. In particular, it includes more realistic uncertainties of the line positions and intensities. The databank contains the calculated line parameters (positions, intensities, air- and self-broadened half-widths and their coefficients of temperature dependence, as well as air- and self- pressure-induced shifts) of the twelve stable isotopic species of CO2. The reference temperature is 296 K, and the intensity cutoff is 10−30 cm−1/(molecule cm−2). More than 530,000 lines covering the 345–14,076 cm−1 spectral range are included in the databank. Comparisons of the new version of the CDSD with UCL, AMES and HITRAN2016 line lists are also given.
