Infrared heterodyne spectroscopy of CO2 in the atmosphere of MarsAn infrared heterodyne spectrometer with a resolving power of 6 million has been used to obtain detailed profiles of the 10-micron absorption lines of CO2 in the atmosphere of Mars. An analysis of the results with an empirical model-atmosphere calculation indicates a nearly pure CO2 atmosphere with an average surface pressure of 5.2 + or - 0.5 mbar in the observed regions, a subsolar surface temperature near 275 K, an atmospheric temperature of 235 to 240 K above the subsolar point, and a lapse rate of 2 K/km.
