GOME-2 captures light reflected from the Earth's surface

Carried on MetOp, the GOME-2 (Global Ozone Monitoring Experiment-2) is a scanning spectrometer that captures light reflected from the Earth's surface and atmosphere. The spectrometer splits the light into its spectral components to map concentrations of atmospheric ozone as well as nitrogen dioxide, sulphur dioxide, other trace gases and ultraviolet radiation.
