TES Regional and Global Atmospheric Chemistry Data Available from the NASA Langley Atmospheric Science
Data Center
The Tropospheric Emission Spectrometer (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 NASA Langley Atmospheric Science Data Center (ASDC) is the archive and distribution center for
data from the TES instrument.
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, HDO, carbon monoxide, methane, and nitric acid for 16 orbits
every other day. Additional products include atmospheric temperature profiles, surface temperatures, and land
surface emissivity A recent reprocessing effort has produced a new version of the data which includes additional
limb species and a new summary product.
In the past year, Level 3 TES products have been released which provide daily or monthly global survey chemical
species data interpolated onto a global latitude/longitude grid at selected pressure levels. Browse images for the
Level 3 and associated Level 2 data are available with these new Level 3 products.
Between global surveys, TES can make 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 40 projects in the discipline areas of Earth's
radiation budget, clouds, aerosols and tropospheric chemistry. Additional information is available from our web
