A methane plume detected by NASA’s AVIRIS-NG in summer 2020 indicates a leaking gas line in oil field in California. The operator subsequently confirmed and repaired the leak. Credit: NASA/JPL-Caltech.

Carbon Mapper: A Collaboration to Map Greenhouse Gas Emissions

April 26, 2021 by Mark Altaweel

A new, non-profit organization, Carbon Mapper, is attempting to create better ways to pinpoint methane and CO2 emissions.

Carbon dioxide emissions increased in East Asia (right) at an average rate of 9.8% per year from 2003 to 2011, but nitrogen oxides increased by ‘only’ 5.8% per year. This indicates a use of cleaner technology in East Asia. North America and Europe, however, show slightly decreasing trends for both gases. The maps show the corresponding spatial pattern as obtained from the satellite data: red corresponds to regions with high values of NOx and CO2, while blue indicates background values.
