GOME is a UV/VIS/near-IR spectrometer.

It has a spectral range of 240–790 nm, which permits the retrieval of the global distribution of ozone and several other trace gases from the spectral data.

The spectral resolution of GOME varies between 0.2 nm and 0.4 nm.

Other geophysical quantities such as macrophysical cloud parameters (cloud cover, cloud top height), surface reflectivity (spectral albedo), and aerosol optical parameters can also be derived.
