Tanager-1

Tanager-1 is the first operational satellite in the Carbon Mapper Coalition Tanager series, launched on 2024-08-16 into a sun-synchronous low Earth orbit.^[1] The satellite carries the Carbon Mapper imaging spectrometer, a pushbroom hyperspectral instrument covering 400-2500 nm at approximately 5 nm spectral sampling.^[2] From its 18.6-24.2 km swath, which varies with look angle, the instrument resolves point-source methane and carbon dioxide super-emitters at 30-43 m ground sampling distance depending on off-nadir angle, reaching up to 30 degrees off-nadir for tasked collections.^[2] First methane and carbon dioxide plume detections from Tanager-1 were confirmed by JPL shortly after activation.^[3] Retrievals are generated from a matched-filter plume detection algorithm applied to at-sensor radiance, yielding column enhancement products for both CH4 and CO2.^[2] The mission targets global monitoring of industrial super-emitters across methane and greenhouse gas flux applications, with tasking supported through the Carbon Mapper data platform.
