Methane and ozone data products from Copernicus Sentinel-5P
04 March 2019
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.
