Abstract:: A set of simulations with the NASA Ames Mars general circulation model (GCM) has been analyzed to define the basic properties and dynamics of quasi-stationary eddy circulations in the winter hemisphere. These circulations, differing substantially from those in low latitudes and the summer hemisphere, extended from the surface to the...

Abstract:: The NASA Ames Mars general circulation and boundary layer models are used as guides to forecast the meteorological environment of the Pathfinder lander site. Based on these models we predict that for a Viking-like atmospheric dust loading, significant vertical wave structure will be seen in the entry temperature profile above...

Abstract:: The NASA Ames Mars General Circulation Model is used to interpret selected results from the Mars Pathfinder atmospheric structure instrument/meteorology (ASI/MET) experiment. The present version of the model has an improved soil thermal model, a new boundary layer scheme, and a correction for non-local thermodynamic equilibrium effects at solar wavelengths....

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:: Tyler, Daniel and Barnes, Jeffrey R.
Abstract:: The Oregon State University Mars MM5 was used in a comprehensive high-resolution study of northern polar summertime circulations. Three simulations (Ls = 120, Ls = 135, and Ls = 150) characterize the changing circulation. The atmosphere is dry, and model dynamics are hydrostatic. A modified TES thermal inertia map provides...

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...
