CEOS Instrument: Multi-spectral thermal infrared imager (HyspIRI)




Instrument:Multi-spectral thermal infrared imager (HyspIRI)
Agency: NASA
Mission: HyspIRI
Status:Proposed
Type:Medium-resolution IR spectrometer
Description:Ecosystem focused mission with measurements of surface and cloud imaging with high spatial resolution, stereoscopic observation of local topography, cloud heights, volcanic plumes, and generation of local surface digital elevation maps, surface temperature and emissivity.
Spatial Resolution: 60 m at nadir; 1 week revisit time
Swath Width: 600 km
Wavebands: 3-5 ?m, 7.5-12 ?m
Technology: Medium-resolution IR spectrometer
Description: Spectrometer operating in MWIR and TIR with spectral resolution typically around 0.1 % to retrieve temperature and humidity profiles from absorption bands of CO2 and H2O in cloud-free or partially cloudy areas, and also total columns of some greenhouse gas species (and coarse profile of O3). Cross-nadir scanning for vertical profiling and total-columns. Many thousands of channels. Spatial resolution typically 10-20 km horizontal, ~ 1 km vertical (referred to the retrieved profile). Applicable in LEO and GEO.
