AB: 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.
