Sentinel 5P - Methane and Ozone data now available

The Copernicus Sentinel-5P mission has been used to produce global maps of two atmospheric gases responsible for making our world warmer: methane, which is a particularly potent greenhouse gas, and ozone, which is a greenhouse gas and a pollutant in the lower part of the atmosphere. The maps give insight into where these gases are coming from.

Launched in October 2017, Sentinel-5P is the first Copernicus satellite dedicated to monitoring our atmosphere. It carries an advanced multispectral imaging spectrometer called Tropomi to image a wide range of air pollutants more accurately and at a higher spatial resolution than ever before.

Prior to making data available to the public, scientists spend months testing and evaluating the information to make sure it is accurate. The mission is already being used to map pollutants such as nitrogen and sulphur dioxide and to monitor the hole in the ozone layer over Antarctica.

And now, data on methane and ozone in the troposphere, which is the lower part of the atmosphere, are available.

While carbon dioxide is more abundant in the atmosphere and therefore more commonly associated with global warming, methane is about 30 times more potent as a heat-trapping gas. It enters the atmosphere mainly from the fossil fuel industry, landfill sites, livestock farming, rice agriculture and wetlands.
