CEOS Instrument: Global Ozone Monitoring by Occultation of Stars




Instrument:GOMOS
Agency: ESA
Mission: Envisat
Status:Operational
Type:Limb-scanning SW spectrometer
Description:Stratospheric profiles of temparature and of ozone, NO2, H20, aerosols and other trace species
Spatial Resolution: 1.7 km vertical
Swath Width: Not applicable
Wavebands: Spectrometers: UV - VIS: 248 - 371 nm and 387 - 693 nm, NIR: 750 - 776 nm and 915 - 956 nm, Photometers: 644 - 705 nm and 466 - 528 nm
Technology: Limb-scanning SW spectrometer
Description: Spectrometers to cover bands in UV, Vis, NIR and SWIR with spectral resolution typically of 0.1-0.3 %, required for atmospheric chemistry. Designed to provide high vertical resolution in the upper troposphere and above by scanning the Earth’s limb. Also, scanning may be performed during occultation of the sun or the moon or bright stars. Thousands of channels. Spatial resolution typically 1-3 km vertical, 300-500 km horizontal. Applicable only in LEO.
