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 N 2 -N 2 , N 2 -H 2 , N 2 -CH 4 , N 2 -H 2 O, N 2 -O 2 , O 2 -O 2 , O 2 -CO 2 , CO 2 -CO 2 , H 2 -H 2 , H 2 -He, H 2 -CH 4 , H 2 -H, H-He, CH 4 -CH 4 , CH 4 -CO 2 , CH 4 -He, and CH 4 -Ar 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.
