Wide-angle Fabry-Perot SWIR imaging spectrometer used by GHGSat methane satellites for facility-scale greenhouse-gas plume imaging.
The GHGSat WAF-P imaging spectrometer is a wide-angle fixed-cavity Fabry-Perot shortwave-infrared sensor family used for targeted greenhouse-gas plume imaging.[1] It spectrally decomposes solar backscattered SWIR radiation for retrieval of absorption features associated with methane, carbon dioxide, and water vapour.[1] The disclosed GHGSat-D heritage instrument operated over 1630-1675 nm with about 0.1 nm spectral resolution and targeted 12 x 12 km scenes.[1] Later WAF-P constellation use is carried at 25 m native ground sampling and 12 km swath; the GHGSat-D demonstrator generation reported 50 x 50 m effective spatial resolution over 12 x 12 km targeted scenes.[1] The sensor is relevant where facility-scale methane plume imaging and industrial greenhouse-gas attribution depend on targeted acquisitions rather than continuous wide-area mapping.[1][2]
