Airborne imaging spectrometers like the next generation Airborne Visible/Infrared Imaging Spectrometer (AVIRIS-NG) are well suited for identifying local methane (CH4) sources by covering large regions with the high spatial resolution necessary to resolve emissions. As part of the ABoVE campaign, AVIRIS-NG surveyed portions of Alaska and Canada that contain potential CH4 emission sources from both anthropogenic and natural sources. While data analysis is ongoing, a number of CH4 plumes have been observed from anthropogenic sources, including gas flaring stacks, coal seams, coal mines, and well pads. Future work will focus on regions with possible natural CH4 sources. Imaging spectrometers permit direct attribution of emissions to individual point sources which is particularly useful given the large uncertainties associated with anthropogenic and natural emissions.
