Mars Global Surveyor: TES Special Products

The Mars Global Surveyor Thermal Emission Spectrometer has acquired a variety of observations, including broadband visible/near-IR data (0.3 to 2.9 micrometers) and broadband thermal IR data (5.1 to 150 micrometers) using bolometers, in addition to spectrometer observations covering 5.8 to 50 micrometers in wavelength (Christensen et al. 2001). The VISIR data have been reduced to Lambert albedo values and gridded at 8 pixels/degree (Christensen et al. 2001). Also, night-time thermal measurements, daytime albedo data, and thermal modeling have been used to generate gridded estimates of surface thermal inertia (Mellon et al., 2000).

These image files (*.img) are binary arrays of 32-bit floating-point pixels. Each data file is accompanied by a PDS label (*.lbl), an ASCII text file that describes the format of the image. The images use a simple cylindrical map projection, described in the file dsmap.cat. These images may be viewed using the display software NASAView.

The images and labels may be downloaded by clicking on the links below. FTP access is also available here. (Read more about anonymous FTP access.)

Questions about these products may be sent to the PDS Geosciences Node, geosci@wunder.wustl.edu.
