The Tropospheric Emission Spectrometer (TES) launched into sun-synchronous
orbit aboard Aura, the third of NASA's Earth Observing System (EOS) spacecraft,
on July 15, 2004. The primary objective of TES is to make global,
three-dimensional measurements of ozone and other chemical species involved in
its formation and destruction.
TES is a high-resolution imaging infrared Fourier-transform spectrometer
that operates in both nadir and limb-sounding modes. TES global survey standard
products include profile measurements of ozone, water vapor, carbon monoxide,
methane, nitrogen dioxide, and nitric acid for 16 orbits every other day. TES
Special Observations are research measurements of targeted locations or
regional transects which are used to observe specific phenomena or to support
local or aircraft validation campaigns.
