Methane and carbon dioxide are powerful greenhouse gases. Fossil fuel power plants are the primary point sources of human carbon dioxide emissions, while methane has diverse anthropogenic point sources, including oil and natural gas infrastructure, landfills, agricultural waste, and human waste treatment. For both methane and carbon dioxide, a small number of sources constitute a large percentage of emissions, providing opportunities for monitoring and in some cases, mitigation. This talk will provide an overview of recent advancements in using airborne hyperspectral remote sensing to measure methane and carbon dioxide point source emissions. Retrieval algorithms and flux estimation will be described, and plume retrievals from a variety of point sources in both the US and India will be shown. Finally, this talk will reveal upcoming challenges and opportunities for this area of research, including the potential for future satellite monitoring of point source greenhouse gas emissions.
