  abstract = {{ A simple synthetic model of the single scattering properties of the
atmospheric Martian dust suitable for radiative transfer calculations in
the infrared is presented. The model is built by modifying the
long-standing Toon et al. [1977] model in order to reproduce accurately
the Mariner 9 observations of the 1971 dust storm, without concern to
the actual dust composition. Compared to previous Martian dust models
which were based on known Earth-analog material, this model should allow
more accurate radiative transfer calculations, until new data from the
upcoming spacecraft missions becomes available. Integrated values
suitable for broad-band climate models are also provided.

  title = {{CO $_{2}$Snowfall on Mars: Simulation with a General Circulation Model}},
  journal = {\icarus},
  year = 1998,
  volume = 131,
  pages = {302-316},
  abstract = {{Although CO$_{2}$snowfall has never been directly observed on
Mars, it has been suggested that such precipitation may explain the
puzzling infrared measurements obtained by Mariner 9 and Viking during
the polar night in each hemisphere. The radiative effect of the snow
would strongly alter the radiative balance of the condensing polar caps
and thus the CO$_{2}$cycle and the global climate. We have
simulated this phenomenon with a general circulation model (GCM). For
that purpose, a new parameterization of CO$_{2}$condensation in
the atmosphere and on the ground has been developed, paying particular
attention to mass and energy conservation and allowing for the possible
sublimation of sedimenting CO$_{2}$ice particles. Atmospheric
condensation may result from radiative cooling on the one hand
(especially when the atmosphere is dust laden) and from adiabatic
cooling in upward motions on the other hand. This latter process can be
very efficient locally. On this basis, we have modeled the effect of the
CO$_{2}$snowfall on the infrared emission by decreasing the local
emissivities when atmospheric condensation was predicted by the model.
This parameterization is based on physical considerations (radiative
transfer through the CO$_{2}$ice particles, snow metamorphism on
the ground). Without tuning the model parameters, we have been able to
accurately reproduce the general behavior of the features observed by
Viking in the thermal infrared. These modeling results support the
CO$_{2}$snowfall scenario suggested from the observations.
Overall, this new parameterization, used in combination with the digital
terrain model topography and with allowance for a varying atmospheric
dust content, allows the GCM to simulate the
CO$_{2}$condensation-sublimation cycle realistically. In
particular, the seasonal variations of the surface pressure recorded by
the Viking Landers can now be reproduced without artificially decreasing
the condensation rate as was done in previous studies.
