Tropospheric Ozone and its precursors from earth system sounding

The TRopospheric Ozone and its Precursors from Earth System Sounding (TROPESS) is considered a bridge to allow the development of a continuous record of ozone and other trace-gas species as a follow-on to the TES mission.

TES

Tropospheric emission spectrometer

NASA’s Tropospheric Emission Spectrometer (TES) instrument aboard the Aura spacecraft was able to help assess the challenges of global climate change and air pollution, as well as improve our understanding of the atmosphere's chemistry. It operated from July 2004 – January 2018 and its high-resolution observations led to new measurements of atmospheric gases that have altered our understanding of the Earth system.
