CEOS Instrument: Stratospheric Aerosol and Gas Experiment-II




Instrument:SAGE II
Agencies: NASA [Primary]
 ROSKOSMOS
Missions: ERBS
 NIMBUS-7
Status:No longer operational
Type:Limb-scanning SW spectrometer
Description:Profiles of ozone, water vapour, NO2, OCIO, aerosols
Spatial Resolution: 0.5 km
Swath Width: N/A
Wavebands: 7 channels, UV - NIR: 0.385 - 1.02 ?m
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.
