The NASA Langley Atmospheric Science Data Center (ASDC) is the archive and distribution center for data from the Tropospheric Emissions Spectrometer (TES) instrument. TES was launched into a sun-synchronous orbit aboard Aura, the third of NASA's Earth Observing System 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.

The TES instrument is a high-resolution imaging infrared Fourier-transform spectrometer that operates in both nadir and limb-sounding modes. TES standard Level 2 data products include global-scale vertical profile and total column measurements of ozone, water vapor, carbon monoxide, methane, and nitric acid for 16 orbits every other day. Additional products include atmospheric temperature profiles, surface temperatures, and land surface emissivity.

In addition, TES makes special observations using its ability to point at a specific location for a few minutes on any given orbit. This capability is used for targets such as gas-emitting volcanoes, for regional air quality studies, and in conjunction with field campaigns.

The ASDC provides data access, services and tools for over 35 projects in the discipline areas of Earth's radiation budget, clouds, aerosols and tropospheric chemistry. Additional information is available from our web site, http://eosweb.larc.nasa.gov.
