The Tropospheric Emission Spectrometer (TES) was flown on the Earth Observing System (EOS) Aura spacecraft launched in July 2004. The primary goal of the TES is the global mapping of tropospheric ozone and its photochemical precursors. The TES is a high spectral resolution infrared imaging Fourier transform spectrometer with spectral coverage from 2.3 to 16.7 micrometers with four single-line arrays optimized for different spectral regions. TES has the
capability to make both limb and down-looking observations. In the limb mode, tropospheric profiles of chemical species are made with a height resolution of 2.3 km from 0 to 30 km. In the down-looking mode, TES provides tropospheric profiles with a spatial resolution of 50 x 5 km (global) and 5 x 0.5 km (local), and a swath of 50 x 180 km (global) and 5 x 18 km (local). Both modes sensing thermal emission from the atmosphere and surface will be used to generate 3-dimensional profiles on a global scale for retrievals of O3, CO, CH4, H2O, and NOy from the surface to the lower stratosphere.

spectroscopy", in Advanced Optical Instrumentation for Remote Sensing of Earth's Surface from Space, vol. 1129, pp 42-51,SPIE,1989.

The TES Principal Investigator is Reinhard Beer.
