Minimize Sensor Description

The GOME (Global Ozone Monitoring Experiment) instrument was an atmospheric chemistry sensor on-board the second European Remote Sensing satellite (ERS-2, 1995 - 2011). GOME was an across-track nadir viewing spectrometer capturing the solar radiation reflected from the Earth's surface and atmosphere to measure a range of atmospheric trace constituents in the troposphere and stratosphere. The spectrometer split the incoming light into its spectral components in the UV/VIS region from 240 nm to 790 nm at a resolution from 0.2 nm (UV, Channel 1) to 0.4 nm (VIS, channel 4). The operational products retrieved from GOME measurements are ozone and nitrogen dioxide total columns as well as cloud information.

A comprehensive description of the GOME instrument can be found in the GOME Users Manual (ESA SP-1182, 1995).
