Tropospheric Emission Spectrometer (TES)
The Tropospheric Emission Spectrometer (TES) is a scientific instrument that sits on a satellite to study Earth's lower atmosphere. It measures the types and amounts of gases, like carbon dioxide and methane, by detecting the specific signals they emit as they interact with sunlight and Earth's heat. TES helps scientists understand air quality, climate change, and how pollutants move and change over time, providing valuable data for environmental research and policy decisions.
