Crater mound formation by wind erosion on Mars
Liam J. Steele, Edwin S. Kite, Timothy I. Michaels
Most of Mars' ancient sedimentary rocks by volume are in wind-eroded sedimentary mounds, but the connections between mound form and wind erosion are unclear. We perform mesoscale s…
Detection and Quantification of Volatiles at Mars using a multispectral LIDAR
Adrian J. Brown, Timothy Michaels, Lori Fenton +14
We present a concept for using a polarization sensitive multispectral lidar to map the seasonal distribution and exchange of volatiles among the reservoirs of the Martian surface a…
The science case for a modern, multi-wavelength, polarization-sensitive LIDAR in orbit around Mars
Adrian J. Brown, Timothy I. Michaels, Shane Byrne +5
We present the scientific case to build a multiple-wavelength, active, near-infrared (NIR) instrument to measure the reflected intensity and polarization characteristics of backsca…
A 3D general circulation model for Pluto and Triton with fixed volatile abundance and simplified surface forcing
Angela Zalucha, Timothy Michaels
We present a 3D general circulation model of Pluto and Triton's atmospheres, which uses radiative-conductive-convective forcing. In both the Pluto and Triton models, an easterly (p…
An investigation of a super-Earth exoplanet with a greenhouse-gas atmosphere using a general circulation model
Angela M. Zalucha, Timothy I. Michaels, Nikku Madhusudhan
We use the Massachusetts Institute of Technology general circulation model (GCM) dynamical core, in conjunction with a Newtonian relaxation scheme that relaxes to a gray, analytica…
The physics of wind-blown sand and dust
Jasper F. Kok, Eric J. R. Parteli, Timothy I. Michaels +1
The transport of sand and dust by wind is a potent erosional force, creates sand dunes and ripples, and loads the atmosphere with suspended dust aerosols. This article presents an…
