Imaging Spectrometer Instrument's Data Shows Methane Intensity

The data captured here is one of the outputs of a September 2023 test conducted at NASA's Jet Propulsion Laboratory of a state-of-the-art imaging spectrometer instrument, which will measure the greenhouse gases methane and carbon dioxide from space. The instrument successfully detected the presence of methane (dark blue line near the top of the rainbow band), a greenhouse gas, in a sample cylinder. The rainbow band shown on a screen here is a measure of the intensity of a spectrum of light.
