Carbon Mapper is a non-profit organization building a global monitoring system for methane and carbon dioxide emissions. The system uses a combination of satellites and aircraft to provide daily to weekly observations of emissions from point sources, such as oil and gas facilities, landfills, and agricultural operations. The data collected by Carbon Mapper is made freely available to the public, and can be used to help governments, businesses, and other organizations reduce their emissions and mitigate climate change.
To help users understand and mitigate emissions, Carbon Mapper has developed a data portal that focuses on human-generated high emission point sources. The portal provides information on methane and carbon dioxide plume locations, imagery, emission rates, and uncertainties from individual facilities around the world. This information is gathered from NASA's next generation Airborne Visible/Infrared Imaging Spectrometer (AVIRIS-NG), ASU's Global Airborne Observatory (GAO), NASA's Earth Surface Mineral Dust Source Investigation (EMIT), and soon, Planet's Tanager constellation.
The plume concentration maps shown here are currently available at spatial resolutions ranging from 3 to 8 meters for airborne (depending on aircraft altitude) or 30 to 60 meters for satellite, allowing for precise attribution to individual emission sources.
The data shown here was collected from airborne campaigns starting in 2016 and satellite campaigns starting in 2023. Coverage exists throughout the world and is on track to grow exponentially with the launch of additional satellites.
