Abstract: 

Correct parameterization of the Collision-induced Absorption (CIA) phenomena is essential for accurate modeling of planetary atmospheres. The HITRAN spectroscopic database provides these parameters in a dedicated section. Here, we significantly revise and extend the HITRAN CIA data with respect to the original effort described in Richard et al. [JQSRT 113, 1276 (2012)]. The extension concerns new collisional pairs as well as wider spectral and temperature ranges for the existing pairs. The database now contains CIA for N2eN2, N2eH2, N2eCH4, N2eH2O, N2eO2, O2eO2, O2eCO2, CO2eCO2, H2eH2, H2eHe, H2eCH4, H2eH, HeHe, CH4eCH4, CH4eCO2, CH4eHe, and CH4eAr collision pairs. The sources of data as well as their validation and selection are discussed. A wish list to eliminate remaining deficiencies or lack of data from the astrophysics perspective is also presented.
