Reliable infrared line lists for 13 CO2 isotopologues up to E′=18,000 cm−1 and 1500 K, with line shape parameters

•Complete set of reliable and continuous IR line lists for 13 CO2 isotopologues.•Covering up to 18,000 cm−1 above zero point energy and 1500 K.•Line position accuracy 0.05 cm−1 or better (for most lines).•Line intensity relative deviations are less than 5-10% for the majority of transitions.•Line shape parameters generated for Mars, Earth, Venus and hotter conditions.

Reliable infrared (IR) line lists are reported for the 13 isotopologues of carbon dioxide in HITRAN notation: 626, 636, 628, 627, 828, 727, 827, 638, 637, 737, 838, 738, and 646. Three IR lists are available for each istotopologue: a complete list at 296 K, a reduced-size list at 296 K, plus a reduced-size list at 1000 K. They are denoted Ames-296K, Ames-296K.reduced and Ames-1000K.reduced. With J up to 150, and energy up to 18,000 cm−1 above the zero point energy, these lists are expected to cover the temperature range up to 1500 K. Line shape parameters including temperature dependence are calculated and reported for four temperature ranges: Mars, Earth, Venus, and Hotter (700-2000 K). Comparisons are made against the available transition data in the HITRAN2012 models. Line position accuracy for most transitions up to 10,000-13,000 cm−1 is better than 0.03-0.05 cm−1. Computed transition intensities agree well with most HITRAN data but there exist suspicious exceptions for isotopologues. These line lists will expedite CO2 IR experimental data analysis and provide the scientific community with trustworthy alternatives for unknown IR bands. These line lists may be combined with existing experimental databases to facilitate the analysis of future laboratory experiments or astronomical observations.
