TES is a satellite instrument designed to measure the state of the earth's troposphere. This infrared Fourier Transform spectrometer will provide key data for studying tropospheric chemistry, troposphere-biosphere interaction, and troposphere-stratosphere exchanges. TES is being built for NASA by the Jet Propulsion Laboratory, California Institute of Technology in Pasadena, California. It was successfully launched into polar orbit aboard NASA's third earth observing systems spacecraft (EOS-Aura) at 10:02 UTC on July 15, 2004.
