## Editorial
The Carbon Mapper Imaging Spectrometer is a VNIR-SWIR imaging spectrometer used on Tanager-1 for greenhouse-gas plume retrievals.[^carbonmapper-specs] It records 421 spectral bands across 400-2500 nm, with 5 nm spectral sampling and 5.5 nm FWHM spectral response.[^carbonmapper-specs] For methane imaging, the spatial resolution is 30 m; swath ranges from 18.6 to 24.2 km depending on look angle, and SNR at 2200 nm ranges from 310 to 655 depending on imaging mode.[^carbonmapper-specs] Tanager-1 made its first methane and carbon dioxide plume detections in 2024, supporting operational use of the sensor after launch.[^jpl-tanager-first-detections] The demonstrated methodology is hyperspectral classification via Tanager-1, with applications in methane plume detection and quantification, carbon dioxide plume detection, and hyperspectral environmental imaging.[^carbonmapper-specs][^carbonmapper-l2b-atbd]
