TES Spectra of Mars Properties
Early Results from MGS Thermal Emission Spectrometer.
This picture shows what Mars Global Surveyor's TES data
look like. This graph is called a "spectrum". The each "squiggly
line" represents the spectrum of a different spot on Mars. The first
spectrum (top) shows some features caused by minerals on the
martian surface. The second spectrum (middle) shows a curve
caused by dust in the atmosphere of Mars. The third (bottom)
shows a curve caused by water ice clouds in the martian atmosphere.
All three spectra show a deep feature caused by the carbon dioxide of
Mars' thin atmosphere. "Wavenumber" represents the frequency (like
the frequency of a radio station) of infrared energy seen by TES.
The "Wavenumber" units are, basically, the number of light vibrations
per centimeter.
