Microwave spectroscopy of the Mars atmosphere.
A study of the use of millimeter-wavelength spectral transitions to investigate the atmosphere of Mars is presented. In the model experiments investigated it is assumed that a spectrometer in the frequency range from 100 to 260 GHz looks into a modest-sized telescope of from 30 to 50 cm aperture from a near-Mars orbit. The molecules H(2)O, CO, O(2), O(3), and H(2)O(2) all have intense spectral ...
متن کاملMars: upper atmosphere.
The thermal structure of the upper atmosphere of Mars has been theoretically investigated. The exospheric temperature, for a pure CO(2) model atmosphere, lies between 400 degrees and 700 degrees K. The origin of the Martian atmosphere is discussed in the light of these results.
متن کاملExtreme Model Atmosphere of Mars
Theoretical models of the atmosphere of Mars have been computed on the basis of our present factual knowledge with a minimum of assumptions. The mathematical method used has proven successful in the past in developing model atmospheres of Earth. Distinct from earlier approaches which have resulted in "best values" or "most likelyconditions," the resultant model atmosphere gives extreme upper an...
متن کاملThe loss of atmosphere from Mars.
Luhmann et al. (1) and Jakosky et al. (2) showed that the Martian atmosphere was eroded (sputtered) by energetic O ions that are formed from escaping 0 and accelerated back into the atmosphere by the solar wind fields. This collisional ejection process appears to explain measured isotope ratios for Ar and N in the martian atmosphere (2, 3) and it may affect the early evolution of this atmospher...
متن کاملSemiannual Oscillations in the Atmosphere of Mars
We report on the first detection of the semiannual oscillation (SAO) in the Martian atmosphere. The semiannual periodicity is found in the difference between dayand night-time atmospheric temperatures, a good proxy for solar tides, measured from Mars Global Surveyor. Simulations with a general circulation model proved that this modulation of tidal amplitudes is a manifestation of the SAO of zon...
