GOME-2 is an optical spectrometer. GOME-2 senses the Earth’s backscattered radiance and extra-terrestrial solar irradiance in the ultraviolet and visible part of the spectrum (240nm–790nm) at a high spectral resolution between 0.26nm and 0.51nm. There are 4,096 spectral points from four detector channels transferred for each individual GOME-2 measurement.
