AVIRIS-NG/GAO:
AVIRIS-NG and GAO are separate aircraft imaging spectrometers deployed in methane monitoring surveys. AVIRIS is operated by NASA’s Jet Propulsion Laboratory. GAO is an ASU Center for Global Discovery and Conservation Science platform.

Carbon Mapper (1 satellite):
A taskable hyperspectral satellite, developed through the Carbon Mapper Coalition and operated by Planet PBC, with both point-source imaging and push-broom mapping capabilities. Expected launch of 2 satellites in 2023. Daily coverage has been reported up to 315,000 sqkm per satellite.

*Value is the result of orbital simulations performed by the satellite operator using RMI's geolocated land area target deck. This value may differ from possible coverage values, since simulations can account for additional factors such as minimal strip length and target depletion.
