Imaging Spectrometer for GHGSat IRIS
The second GHGSat IRIS microSat capable of monitoring greenhouse gas (GHG) emissions of any industrial site in the world, ready for verification in MPBC’s Clean Room.
GHGSat IRIS (GHGSat-C1) is an upgraded instrument from GHGSat CLAIRE (GHGSat-D) featuring high-resolution, narrow-bandwidth imaging spectrometer designed to fly on a 15-kg microSat. With a polar orbit at 500-km altitude, it surveys the earth’s surface with observations of selected 15 × 15 km areas of interest. It senses the luminosity of earth areas in bands relevant to greenhouse gases such as CO2 and CH4.
