Minimize GOME
Instrument image

GOME is a nadir-scanning ultraviolet and visible spectrometer for global monitoring of atmospheric Ozone, launched on-board ERS-2 in April 1995. Since summer 1996, ESA has been delivering to users three-day GOME global observations of total ozone, nitrogen dioxide and related cloud information. A key feature of GOME was its ability to detect other chemically active atmospheric trace-gases as well as aerosol distribution.

New ERS-2 GOME Level 1 v5.1 dataset available online

20 June 2018

The post-operational full-mission reprocessing campaign of ERS-2 GOME consolidated data has been completed with an improved instrument processor version (Level-0-to-1 GDP Version 5.1). A new GOME Level 1b dataset has been generated for the 16-year mission period. The new data bring relevant quality improvements for the revised calibration approach, compensating aging and instrument degradation, and provide enhanced accessibility.
