CEOS Instrument: Stratospheric Aerosol and Gas Experiment

Agency: NASA
Mission: SAGE-III
Status:Being developed
Type:Limb-scanning SW spectrometer
Description:Limb-viewing measurements of aerosols, O3, OClO, N2O NO3, H2O, temperature and pressure in the straosphere and mesophere
Spatial Resolution: 1-2 km vertical
Swath Width: N/A
Wavebands: Nine spectral regions between 290 - 1550 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.
