The CO2 spectroscopic databank of rotation-vibration line parameters developed at the Institute of Atmospheric Optics and called CDSD (Carbon Dioxide Spectroscopic Databank) is presented. The databank is based on effective Hamiltonian and effective dipole moment theoretical models globally describing high resolution spectra of CO2 molecule in its electronic ground state. Parameters of the models are fitted to the measured positions and intensities of the spectral lines collected from the literature. Three versions of the databank are discussed. The first one is CDSD-296 aimed at atmospheric applications. The second one (CDSD-1000) is suited for the 296-2500°K temperature range. Finally, CDSD-4000 is suited for temperatures 2500-5000°K. The utilization of all versions of CDSD databank in a wide range of atmospheric and high temperature applications is also discussed.
