The Global Ozone Monitoring Experiment (GOME) was launched on April 21st 1995 on board the second European Remote Sensing Satellite (ERS-2). This instrument can measure a range of atmospheric trace constituents, with the emphasis on global ozone distributions.

GOME is a nadir-viewing spectrometer that measures the solar radiation scattered by the atmosphere in the ultraviolet and visible spectral region (240 to 790 nm). The sensor has a high spectral resolution of 0.2 to 0.4 nm sensed by four individual linear detector arrays each with 1024 detector pixels. The field of view may be varied in size from 320 km x 40 km to 960 km x 80 km. For further information and the mission objectives see the sensor information sheet.

GOME level-1 (radiances / reflectances) and level-2 (trace gas amounts) products are computed from level-0 (raw) data using the GOME Data Processor (GDP) system which was designed and developed by the German Remote Sensing Data Center (DFD) of DLR in cooperation with the Institute of Remote Sensing (University of Bremen/Germany), the Smithonian Astrophysical Observatory (Harvard, Cambridge/MD, USA), the University of Heidelberg (Germany), the Koninklijk Nederlands Meteorologisch Instituut (KNMI, The Netherlands), and other institutions involved in the GOME Science Advisory Group.
GDP is the only operational off-line ground segment of the GOME sensor. The operational processing of GOME data is done at the German D-PAF which is part of DFD. For details about the quality of the level-1/-2 product refer to the disclaimer document or the GOME Quality Survey pages as provided by BIRA-IASB (Belgian Institute for Space Aeronomy) and UT-LAP (University of Thessaloniki).

On December 15, 2004 GOME Level 2 data have been released with GDP version 4.0.
