Absorption cross section of CO₂ for wavelengths longer than 195 nm at 465 K, 510 K, 560 K, 610 K, 655 K, 750 K, and 800 K, plotted with the cross section at ambient temperature (black) and the absorption cross sections measured at shorter wavelengths and presented in Fig. 7 (300 K, 410 K, 480 K, and 550 K). The absorption cross sections calculated with Eq. (6) are plotted with the same color coding.
