Abstract

Global Ozone Monitoring Experiment (GOME) is a grating spectrometer designed to monitor from the ESA satellite ERS-2 absorption by ozone and trace gases in the earth atmosphere. The instrument works in the spectral range 240-790 nm, with a spectral resolution of 0.2 nm and a spatial resolution of 40 X 40 km². GOME makes use of high density holographic gratings as dispersing elements, and cooled photodiode arrays of 1024 pixels as detectors. Its characteristics, as well as the in flight calibration means, permit to use both differential optical absorption spectrometry and backscattering in the ultra-violet as retrieval methods. This paper describes the main features of the instrument, the results of the test campaign performed on the engineering model and the concepts adopted for ground and in- flight calibration.
