3D volumetric visualisation of global atmospheric methane (CH4) emission and transport on 25th February 2018. Methane is a powerful greenhouse gas. It is produced by modern agricultural practices, activities related to oil, gas, and coal extraction, and the decomposition of organic matter. The height of Earth's atmosphere and topography have been vertically exaggerated and appear approximately 50-times higher than normal in order to show the complexity of the atmospheric flow.
