The U.S. National Aeronautics and Space Administration (NASA) three-dimensional view of methane concentrations worldwide combines datasets from emissions inventories and simulations of wetland sources into a high-resolution model.

The model also incorporated data from NASA field campaigns like the Arctic Boreal Vulnerability Experiment, along with data from the Japanese Space Agency's Greenhouse Gases Observing Satellite, and the Tropospheric Monitoring Instrument on the European Space Agency's Sentinel-5P satellite.

The model calculates methane emissions based on known processes for certain land-cover types and the atmospheric chemistry that breaks down and removes methane from the air.

The visualization displays methane's migration and behavior patterns over time based on a weather model, and highlights major concentrations in the Amazon River basin, India, China, and the Arctic.
