Equivalence relations for Mueller matrix symmetries of laboratory, LIDAR and planetary scattering geometries
Adrian J. Brown
Symmetry relationships for optical observations of matter generally fall into several common scattering geometries. The 'planetary' configuration is preferred among a group of obse…
Interannual observations and quantification of summertime H2O ice deposition on the Martian CO2 ice south polar cap
Adrian J. Brown, Sylvain Piqueux, Timothy N. Titus
The spectral signature of water ice was observed on Martian south polar cap in 2004 by the Observatoire pour l'Mineralogie, l'Eau les Glaces et l'Activite (OMEGA) (Bibring et al.,…
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…
Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) north polar springtime recession mapping: First Three Mars years of observations
Adrian J. Brown, Wendy M. Calvin, Scott L. Murchie
We report on mapping of the north polar region of Mars using data from the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) instrument. We have observed three Mars Year…
Hydrothermal formation of Clay-Carbonate alteration assemblages in the Nili Fossae region of Mars
Adrian J. Brown, Simon J. Hook, Alice M. Baldridge +6
The Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) has returned observations of the Nili Fossae region indicating the presence of Mg- carbonate in small (<10km sq2),…
Louth Crater: Evolution of a layered water ice mound
Adrian J. Brown, Shane Byrne, Livio L. Tornabene +1
We report on observations made of the ~36km diameter crater, Louth, in the north polar region of Mars (at 70°N, 103.2°E). High-resolution imagery from the instruments on the Mars R…
The MARTE VNIR Imaging Spectrometer Experiment: Design and Analysis
Adrian J. Brown, Brad Sutter, Stephen Dunagan
We report on the design, operation, and data analysis methods employed on the VNIR imaging spectrometer instrument that was part of the Mars Astrobiology Research and Technology Ex…
MR PRISM - Spectral Analysis Tool for the CRISM
Adrian J. Brown, Michael Storrie-Lombardi
We describe a computer application designed to analyze hyperspectral data collected by the Compact Infrared Spectrometer for Mars (CRISM). The application links the spectral, imagi…
Hydrothermal alteration at the Panorama Formation, North Pole Dome, Pilbara Craton, Western Australia
Adrian J. Brown, Thomas J. Cudahy, Malcolm R. Walter
An airborne hyperspectral remote sensing dataset was obtained of the North Pole Dome region of the Pilbara Craton in October 2002. It has been analyzed for indications of hydrother…
Hyperspectral imaging spectroscopy of a Mars analogue environment at the North Pole Dome, Pilbara Craton, Western Australia
Adrian J. Brown, Malcolm Walter, Thomas Cudahy
A visible and near infrared (VNIR) to shortwave infrared (SWIR) hyperspectral dataset of the Early Archaean North Pole Dome, Pilbara Craton, Western Australia, has been analysed fo…
SWIR Investigation of sites of astrobiological interest
Adrian J. Brown, Malcolm Walter, Thomas Cudahy
Rover missions to the rocky bodies of the Solar System and especially to Mars require light- weight, portable instruments that use minimal power, require no sample preparation, and…
