CEOS EO HANDBOOK – INSTRUMENT SUMMARY - OSIRIS -
Full Name Optical Spectrograph and Infra-Red Imaging System Status Operational
Instrument Agencies CSA, SNSB Maturity
Instrument Type Atmospheric chemistry Geometry Limb-scanning
Instrument Technology Limb-scanning SW spectrometer Sampling Sounding
Data Access Open Access Data Format HDF-EOS
Measurements and Applications Detects aerosol layers and abundance of species such as O3, NO2, OClO, BrO and NO. Consists of spectrograph and IR imager.
Resolution Summary Spectrograph 1 km at limb, Imager 1 km in vertical
Swath Summary N/A, but measures in the altitude range 5 - 100 km
Accuracy Summary Depends on species. Ozone meets requirements for trend analysis
Waveband Summary Spectrograph: UV - NIR: 0.28 - 0.80 µm; IR Imager: NIR: 1.26 µm, 1.27 µm, 1.52 µm
UV (~0.01 µm - ~0.40 µm)
VIS (~0.40 µm - ~0.75 µm)
NIR (~0.75 µm - ~1.3 µm)
SWIR (~1.3 µm - ~3.0 µm)
