The Sentinel5P satellite will measure NO2, O3, HCHO, SO2, CO, CH4 as well as clouds and aerosols in the atmosphereThe Sentinels are a fleet of satellites designed specifically to deliver the wealth of data and imagery that are central to the European Commission’s Copernicus program. This unique environmental monitoring program is making a step change in the way we manage our environment, understand and tackle the effects of climate change and safeguard everyday lives.
Sentinel-5 Precursor – also known as Sentinel-5P – is the first Copernicus mission dedicated to monitoring our atmosphere. The satellite carries the state-of-the-art Tropomi instrument to map a multitude of trace gases such as nitrogen dioxide, ozone, formaldehyde, sulphur dioxide, methane, carbon monoxide and aerosols – all of which affect the air we breathe and therefore our health, and our climate.
With a swath width of 2600 km, it will map the entire planet every day. Information from this new mission will be used through the Copernicus Atmosphere Monitoring Service for air quality forecasts and for decision-making.
Tropomi – a spectrometer – will map the global atmosphere every day with a resolution as high as 7 km × 3.5 km. At this resolution, air pollution over cities can be detected.
The mission will also contribute to services such as volcanic ash monitoring for aviation safety and for services that warn of high levels of UV radiation which can cause skin damage. In addition, scientists will also use the data to improve our knowledge of important processes in the atmosphere related to the climate and to the formation of holes in the ozone layer.
