Evidence suggests that Earth and its atmosphere are changing due to both natural and human-induced effects. Scientists need to understand current atmospheric processes so they will be better able to determine future changes and assess the consequences for society.
The upper atmosphere is one of the least explored regions of Earth, making accurate information about it essential for global climate change studies. A NASA spaceborne instrument called SABER (Sounding of the Atmosphere using Broadband Emission Radiometry) has allowed researchers to learn more about the upper atmosphere by helping produce the first comprehensive global measurements of this region.
SABER provides a never-before-seen view of the atmosphere and paves the way for a new area of science. SABER, built by Utah State University Space Dynamics Laboratory and managed by NASA Langley Research Center, is one of four instruments on the TIMED (Thermosphere, Ionosphere, Mesosphere, Energetics and Dynamics) spacecraft, which launched in late 2001.
