Title: THE NEW VERSION OF THE HITRAN DATABASE: EXAMPLE OF CARBON DIOXIDE LINE PARAMETERS
Creators: Rothman, Laurence S.; Wattson, R. B.; Gamache, Robert R.

Abstract: A new version of the atmospheric absorption line parameter compilation (HITRAN database) has been implemented. The data that have been archived in the versions prior to this time have consisted of a minimal set of four fundamental parameters for each discrete line transition above a chosen threshold required for calculations of atmospheric transmission and $radiance^{1}$. The structure of the database has been expanded to allow for additional molecular parameters, such as self-broadened linewidths, temperature dependence of halfwidths. line shifts, and transition moments, that extend the capabilities to upper atmospheric comparisons and to satisfy proposed satellite experimental techniques. Major updates of the parameters have occurred; the specific case of $CO_{2}$ will be presented. Major improvement has been effected by new line position calculations and the assimilation of recent laboratory measurements of $intensities^{2}$ as well as the new theoretical treatment of parallel band $intensities^{3}$ and recent linewidth $measurements^{4}$.
