As we prepare to meet the challenges of global climate change and pollution, we urgently need to improve our understanding of the atmosphere's chemistry. TES is making a vital contribution to this effort as one of four instruments aboard NASA's Aura satellite. TES focuses on the troposphere, the layer of atmosphere that stretches from the ground to the altitude at which airplanes fly. With very high spectral resolution, TES can distinguish concentrations of gases at different altitudes, a key factor in understanding their behavior and impact. It's the first orbiting instrument able to do this with ozone, a very important chemical with regard to both global warming and air pollution.
