Carbon Mapper Methane Plume Detections is a Level-4 point-source methane and CO2 super-emitter product. It uses a column-wise matched filter algorithm to retrieve CH4 and CO2 plumes from imaging spectrometer data. Source instruments include Tanager-1 (launched 2024-08-16, commissioned January 2025), NASA EMIT on the International Space Station, and AVIRIS airborne data.[1]
At Tanager-1 operating altitude of 406 km, ground sample distance is approximately 30 m and swath width is approximately 19 km at nadir, extendable to approximately 26 km at 30-degree off-nadir pointing. Spectral coverage is 380-2500 nm at 5 nm sampling and 5.5 nm FWHM.[1] Methane detection limit ranges from 64 to 126 kg/hour under reference conditions (25% albedo, 45-degree solar zenith angle, 3 m/s wind).[1]
The collection mode is tasked: coverage is not continuous and targets are scheduled. This limits applicability to systematic global monitoring without prior tasking.[2]
Products are accessible at data.carbonmapper.org and via STAC API at https://api.carbonmapper.org/api/v1/stac/. Non-commercial access is free upon registration. Commercial use requires a direct agreement with Carbon Mapper.[2][3]
