Air quality and climate change are important challenges for society. As part of Europe's environmental monitoring Copernicus programme, the Sentinel-5 Precursor satellite will be launched towards the end of the year. It carries the Tropomi tropospheric monitoring instrument to measure atmospheric trace gases such as nitrogen dioxide, ozone, carbon monoxide and methane. It will provide daily worldwide measurements for the next seven years. The Copernicus Atmosphere Monitoring Service will use the
