CEOS Instrument: Atmospheric Chemistry Experiment (ACE) Fourier Transform Spectrometer

Agency: CSA
Mission: SCISAT-1
Type:Limb-scanning IR spectrometer
Description:Measure and understand the chemical processes that control the distribution of ozone in the Earth's atmosphere, especially at high altitudes.
Spatial Resolution: N/A
Swath Width: N/A
Wavebands: SWIR - TIR: 2 - 5.5 ?m, 5.5 - 13 ?m (0.02 cm-1 resolution)
Technology: Limb-scanning IR spectrometer
Description: Spectrometer operating in MWIR and TIR with spectral resolution typically around 0.01 % required for atmospheric chemistry. Designed to provide high vertical resolution in the upper troposphere and above by scanning the Earth’s limb. Many thousands of channels. Spatial resolution typically 1-3 km vertical, 300-500 km horizontal. Applicable only in LEO.
