Creator:: Barnes, Jeffrey R. and Haberle, Robert M.
Abstract:: Analysis of simulations performed with the NASA/Ames Mars GCM shows that under dusty conditions the Northern Hemisphere winter solstice circulation becomes characterized by a zonally averaged state in which the potential vorticity at upper levels is very small outside of high latitudes. The available observational data-in particular the 15-µm observations...

Abstract:: Modeling of slope flow circulations in idealized axisymmetric craters is used to understand (1) the large surface pressure amplitude observed in Gale Crater by the Rover Environmental Monitoring Station and (2) the shallow convective boundary layer (CBL) suggested by Curiosity imagery. Air temperatures vary within craters with greater amplitudes than...

Abstract:: For a key season in the annual water cycle (L[subscript s]~120°) a mesoscale model is used to study atmospheric water vapor and water ice clouds in the northern polar region of Mars. Model results at high-resolution (15 km) allow the examination of various mesoscale aspects of the circulation in this...

Daniel, Cantor, Bruce A., Dwyer-Cianciolo, Alicia M., Fergason, Robin L., Hinson, David P., Justh, Hilary L., Kass, David M., Lewis, Stephen R., Mischna, Michael A., Murphy, James R., Rafkin, Scot C. R., Tyler, Daniel, and Withers, Paul G.
Abstract:: The Mars Science Laboratory mission aims to land a car-sized rover on Mars’ surface and operate it for at least one Mars year in order to assess whether its field area was ever capable of supporting microbial life. Here we describe the approach used to identify, characterize, and assess environmental...

Creator:: Hollingsworth, Jeffery L. and Barnes, Jeffrey R.
Abstract:: Mariner 9 and Viking spacecraft observations provided evidence for planetary-scale, wavelike disturbances in the Mars winter atmosphere. Possible sources of the wave activity are dynamical instabilities, for example, barotropic and / or baroclinic instabilities. Other candidate sources are forced. quasi-stationary planetary waves—waves that arise predominantly via zonally asymmetric surface properties....
