A Method to Obtain Dust and Ice Cloud Optical Depths over the Cold Polar Surfaces of Mars

Horne, David J

Abstract Details

2007, Doctor of Philosophy, University of Toledo, Physics.
The Mars Global Surveyor Thermal Emission Spectrometer (TES) instrument has returned over 200 million thermal infrared spectra of Mars taken between March 1999 and August 2004. This represents one of the most complete records of spatial and temporal changes of the Martian atmosphere ever recorded by an orbiting spacecraft. Previous reports of the standard TES retrieval of aerosol optical depth have been limited to those observations taken over surfaces with temperatures above 210 K, limiting the spatiotemporal coverage of Polar Regions with TES. Here, we present an extension to the standard TES retrieval that models the effects of cold surfaces below 200K. This modification allows aerosol optical depth to be retrieved from TES spectra over a greater spatiotemporal range than was previously possible, specifically in Polar Regions. This new algorithm is applied to the Polar Regions to show the seasonal variability in dust and ice optical depth for the complete temporal range of the TES database (Mars Year 24, Ls= &104deg;, 1 March 1999 to Mars Year 27, Ls= &82deg; , 31 August 2004).
