Atmospheric and Oceanic Optics is the English edition of the Russian monthly academic journal Optika Atmosfery i Okeana translated and published by the Institute of Atmospheric Optics.
The Atmospheric and Oceanic Optics presents experimental and theoretical articles relevant to a wide range of problems of atmospheric and ocean optics, ecology, and Earth's climate. The journal's coverage includes: - scattering and transfer of optical waves, - spectroscopy of atmospheric gases, - turbulent and nonlinear optical phenomena, - adaptive optics, - remote (ground-based, airborne, and spaceborne) sensing of the atmosphere and the surface, - methods for solution of inverse problems, - new equipment for optical investigations, - development of computer programs and databases for optical studies.
Specialized issues of the journal regularly present proceedings of regional and international scientific conferences and meetings, such as Siberian Aerosols and Atomic and Molecular Pulsed Lasers (AMPL). Various topical issues are devoted to studies of atmospheric ozone, adaptive, nonlinear, and coherent optics, regional climate-ecological monitoring, and other subjects.

The shapes of the extreme wings of self-broadened CO2(lines have been investigated)in three spectral regions near 7000, 3800, and 2400 cm-1. Absorption measurements have been made on the high-wavenumber sides of band heads where much of the absorption by samples at a few atm is due to the extreme wings of strong lines whose centers occur below the band heads. New information has been obtained about the shapes of self-broadened CO2 lines as well as CO2 lines broadened by N2, O2, Ar, He, and H2. Beyond a few cm-1 from the line centers, all of the lines absorb less than Lorentz-shaped lines having the same half-widths. The deviation from the Lorentz shape decreases with increasing wavenumber, from one of the three spectral regions to the next. The absorption by the wings of H2- and He-broadened lines is particularly low, and the absorption decreases with increasing temperature at a rate faster than predicted by existing theories.
