PDS: The Planetary Atmospheres Node
The Thermal Emission Spectrometer (TES)
Location and side view of TES
Description of the Instrument
TES has three components spanning infrared and visible wavelengths: a Michelson interferometer, a broadband radiance sensor, and a solar reflectance sensor. The interferometer covers the thermal IR with a wavelength range from 6 to 50 microns (~1650-200 cm-1) with 5 and 10 cm-1 spectral sampling (~10 and 20 cm-1 resolution). The broadband sensor covers 5.5 to 100 microns. The solar reflectance sensor spans 0.3 to 2.7 micron. Each sensor has six detectors arranged in a 3 by 2 array, each with a field of view of 8.3-mrad. This translates to a spatial resolution of 3 km from the MGS orbit.
Location of the Data
The main data consists of raw and calibrated thermal infrared radiance spectra, visual and thermal bolometric radiance measurements, and atmospheric and surface properties derived from this data. TES data are produced by the TES Science Team at Arizona State University and archived by the PDS Geosciences Node.
