Caption: Maps showing the global distribution of atmospheric methane (CH4) from 2003-2004 (top) and 2010-2011 (bottom). Concentration, in parts per billion (ppb), is colour-coded, from purple (low), through blue and green to yellow and red (high). The scale changes for the two images, as in 2010-2011 average global methane is approximately 30 ppb higher than 2003-2004. High emission areas include wetlands in Siberia and the USA, rice fields in China, and coal and gas mining in the USA. 2003-2004 data from the Sciamachy instrument on ESA's Envisat satellite. 2010-2011 data from the TANSO-FTS (Infrared Fourier Transform Spectrometer) instrument on Japan's GOSAT (Greenhouse Gases Observing Satellite) satellite.
