FOR several years the most widely accepted value of 90 mbar for the surface pressure on Mars had been based on visible photometric and polarimetric work, particularly by Dollfus1 (cf. de Vaucouleurs2 for a detailed discussion). Recently, however, a value of 25 ± 15 mbar has been derived by Kaplan, Münch, and Spinrad3 from a curve-of-growth analysis of pressure-broadened carbon-dioxide vibration-rotation lines in near infra-red Martian spectra. A possible explanation of the discrepancy is that…

A summary of results of observations of the polarization of Mars shows that surface pressure determinations from these data have not yielded satisfactory results, and Polarization measurements show that limonite is one, but by no means unique, possibility for a major constituent of the surface.

MIE SCATTERING AND THE MARTIAN ATMOSPHERE

It has been suggested that the discrepancy between radio occultation determinations of the Martian atmospheric surface pressure (3.8 to 7 mb) and those deduced from optical polarization measurements

Ultraviolet Spectroscopy Experiment for Mariner Mars 19711

The Mariner Mars 1971 ultraviolet spectrometer will obtain spectra in the 1100 to 3490 A wavelength range. The spectral features in this range will help to characterize the Martian atmosphere in a

Mars: Compatible Determinations of Surface Pressure through Particle Scattering

The number of scattering particles required to bring the visual polarimetric and ultraviolet photometric estimates of the surface pressure of Mars into agreement are calculated and lie within the range of pressures determined spectroscopically.
