The world's first space-based system to help identify specific sources of greenhouse gas emissions is now circling the Earth.

The main unit in the network, an orbiter called the Tropospheric Monitoring Instrument (Tropomi), is a package of state-of-the-art sensors launched by the European Space Agency (ESA) in October. By December, it had begun to map the plumes of methane, carbon dioxide, nitrogen oxides, carbon monoxide and various aerosols over industrial facilities and cities as it passed over Europe, Asia, Africa and South America.
