CEOS Instrument: IR spectrometer (CLARREO)




Instrument:IR spectrometer (CLARREO)
Agency: NASA
Missions: CLARREO-1
 CLARREO-3
Status:No longer considered
Type:High-resolution nadir-scanning IR spectrometer
Description:Absolute spectrally-resolved measurements of terrestrial thermal emission with an absolute accuracy of 0.1 K in brightness temperature. The measurements cover most of the thermal spectrum.
Spatial Resolution: 1 cm-1; 100 km footprint
Swath Width: 100 km
Wavebands: 200 to 2000 cm-1
Technology: High-resolution nadir-scanning IR spectrometer
Description: Spectrometer operating in MWIR and TIR with spectral resolution typically around 0.01 % required for atmospheric chemistry. Earth viewing so as to measure vertical profiles and total columns in cloud-free or partially cloudy areas. Cross-nadir scanning for vertical profiling and total-columns. Many thousands of channels. Spatial resolution typically 5-10 km horizontal, ~ 1 km vertical (referred to the retrieved profiles). Applicable only in LEO.
