London: A European satellite tracking the levels air pollutants around the world has beamed back new views of the Earth's atmosphere, including images of pollution drifting away from power plants in India. The worst of this pollution runs from north of Patna in Bihar to south of Raipur in Chhattisgarh, scientists said.

The Sentinel-5P satellite is designed to make daily global maps of the gases and particles that pollute the air.

The first sample images released by mission scientists show plumes of nitrogen dioxide flowing away from power plants and traffic-choked cities. S5P has even captured the ash and sulphur emissions from Agung volcano on the Indonesian island of Bali, which is in the midst of a big eruption.

Researchers from the Netherlands Met Office (KNMI) still need to complete five months of calibration work to get the satellite's data ready for public use. When fully operational, the new Sentinel will be an extremely powerful tool to monitor air quality, according to principal investigator Pepijn Veefkind.

"It's been amazing to see how quickly we were able to get the satellite working. This is a big improvement on what we've been able to do before.

In just a week, we've got more data out of Sentinel-5P than in several years of operation of a previous mission," Veefkind told 'BBC News'.

Sentinel-5P is the latest spacecraft in a fleet of Earth observers being commissioned by the European Union and the European Space Agency.
