Abstract:

In the original publication, there has been a discrepancy between values mentioned in the text of Sect. 4.3.3 and in Table 1. The corrected version is provided here: Wrong: The gravity field harmonic coefficients up to an average degree strength of 130 (∼145 km) are generated together with corrections to the spin rate and to the pole right ascension and declination. Correct: The gravity field harmonic coefficients up to an average degree strength of 200 (∼105 km, see Table 1) are generated together with corrections to the spin rate and to the pole right ascension and declination.

Abstract:

Collisional parameters of H2O with CO2 are currently missing from international spectroscopic databases, although they are essential for accurate modeling of water vapor in CO2-rich planetary atmospheres. In this study, high-resolution infrared spectra of H2O broadened by CO2 were recorded using a Fourier Transform Spectrometer in the 1.18 and 2.34 µm spectral regions. CO2-collisional parameters for selected H2O transitions were derived through a multispectrum fitting procedure employing both Voigt and quadratic speed-dependent Voigt profiles. Furthermore, calculations based on the semi-classical Complex Robert-Bonamy-Ma formalism were performed to estimate CO2-broadened half-widths, line shifts, and their temperature dependencies across various atmospheric transparency windows. It results in a strong agreement between theoretical predictions and experimental data. Finally, the shared calculated linelist, obtained for a wide range of transitions, can be directly applied to radiative transfer modeling of atmospheres primarily composed of carbon dioxide
