Simplified interpretation of Martian transmission spectra

A highly simplified procedure for the interpretation of Kuiper's Martian and telluric transmission measurements in the 2 μ region is shown to lead to a Martian surface pressure estimate of about 5 ± 1 mbar.

Approximate estimates for the surface pressure of mars based on infrared transmission data in the 2μ region

The surface pressure of Mars has been estimated on the basis of Kuiper's 1964 observations by utilizing a non-overlapping spectral-line model for the CO 2 bands on Mars, with absorption determined by spectral lines lying in the square-root region of the curves of growth. Neglecting shielding by the opaque line centers in the atmosphere of the Earth, we obtain a lower bound for the Martian surface pressure ( p s♂ ) min of 1·6 mbar. Introduction of approximate corrections for “nearly black” line centers yields a “best estimate” for p s♂ of 6·1 mbar; the uncertainty in this value is largely determined by unknown errors in the measurements and by lack of information concerning spectral line structure in the far line wings.
