Japan Satellite Observes Methane Concentrations in China, India

High concentrations of methane emissions from man-made sources have been observed in parts of China and India, according to an analysis of data collected by a Japanese satellite.

Japan’s Gosat satellite is the world’s first specifically designed to monitor greenhouse gases from space, according to a statement from Japan’s Ministry of the Environment and partners.

Data gathered between June 2009 and December 2012 shows methane concentrations tend to be high in areas where populations are most dense, according to the statement.

Large-scale farming areas and sites for production and processing of oil and natural gas also see higher concentrations, according to the statement.

Methane concentrations from man-made sources were higher in areas around Chengdu and Chongqing in China, and regions around Kolkata and Meghalaya in India and Dhaka, Bangladesh, according to the study. Parts of Pakistan, Brazil, the U.S. and Russia also had areas of high concentrations.
