Abstract :
The HyperSpectral Imager for Climate Science (HySICS) is a spatial/spectral spectrometer for viewing Earth scenes with the ~0.2% (1-σ) radiometric accuracy needed for climate studies. Covering the reflected solar spectral region from 350 to 2300 nm with 6 nm resolution, this instrument will provide 0.5 km spatial resolution while covering a 100 km ground swath from low Earth orbit. A single focal plane array spans the entire spectral region, allowing for reduced mass, volume, and complexity for space flight applications compared to instrument designs with separate spectral regions.
