Methane in the Earth’s troposphere

Methane in the Earth’s troposphere

Fig. 4.24 . The global distribution of methane in the lower parts of the Earth’s atmosphere, known as the troposphere. This image was taken from the Atmospheric Infrared Sounder Experiment aboard the Aqua spacecraft in August 2005. Such images will help identify sources of this heat trapping, greenhouse gas, as well as its seasonal and multi-year variation and its transport around the globe. (Courtesy NASA/JPL.)
