Topography Driven Variation In Argon Abundance As Measured by the GRS on Mars Odyssey
Abstract
The GRS on Mars Odyssey measures the 1294 keV gamma ray line of Mars atmospheric argon. We present data from discrete longitudes centered over Hellas Basin, Tharsis Montes, and a sector of no particular topographic form other than the dichotomy between the southern highlands and northern lowlands. Some differences in the argon abundance as a function of season are seen between these longitude sectors.
