Air pollution is the largest environmental health risk in Europe and significantly impacts the health of the European population, particularly in urban areas.
Following on from the Sentinel-5P satellite – the first Copernicus mission dedicated to monitoring our atmosphere – the Sentinel-4 and Sentinel-5 missions will take current air quality measuring capabilities to the next level.
Together, the Sentinel-4 and -5 missions will provide information on atmospheric variables in support of European policies. This will include the monitoring of air quality, stratospheric ozone and solar radiation, and climate monitoring.
This video features interviews with Giorgio Bagnasco, Sentinel-4 Mission Project Manager, Ben Veilhelmann, Sentinel-4&5 Mission Scientist and Didier Martin, Sentinel-5 Mission Project Manager.

We are Europe’s gateway to space. Our mission is to shape the development of Europe’s space capability and ensure that investment in space continues to deliver benefits to the citizens of Europe and the world. Check out https://www.esa.int/ to get up to speed on everything space related.
This animation, using data from the Copernicus Sentinel-5P satellite, shows the nitrogen dioxide emissions from 20 December 2019 until 16 March 2020 – using a 10-day moving average. The drop in emissions in late-January is visible, coinciding with the nationwide quarantine, and from the beginning of March, the nitrogen dioxide levels have begun to increase.

New data from the Copernicus Sentinel-5P satellite reveal the decline of air pollution, specifically nitrogen dioxide emissions, over Italy. This reduction is particularly visible in northern Italy which coincides with its nationwide lockdown to prevent the spread of the coronavirus.
The animation shows the fluctuation of nitrogen dioxide emissions across Europe from 1 January 2020 until 11 March 2020, using a 10-day moving average. These data are thanks to the Tropomi instrument on board the Copernicus Sentinel-5P satellite which maps a multitude of air pollutants around the globe.
Claus Zehner, ESA’s Copernicus Sentinel-5P mission manager, comments, “The decline in nitrogen dioxide emissions over the Po Valley in northern Italy is particularly evident.
“Although there could be slight variations in the data due to cloud cover and changing weather, we are very confident that the reduction in emissions that we can see, coincides with the lockdown in Italy causing less traffic and industrial activities.”
Josef Aschbacher, ESA’s Director of Earth Observation Programmes, says, “Copernicus Sentinel-5P Tropomi is the most accurate instrument today that measures air pollution from space. These measurements, globally available thanks to the free and open data policy, provide crucial information for citizens and decision makers.”
The coronavirus disease (COVID-19) was recently declared a pandemic by the World Health Organisation, with more than 125 000 current cases of the disease reported globally. In Italy, the number of coronavirus cases drastically soared making it the country with the largest number of cases outside of China.
In an attempt to reduce the spread of the disease, Italy’s Prime Minister Giuseppe Conte announced a lockdown of the entire country – closing schools, restaurants, bars, museums and other venues across the country.
The Sentinel-5 Precursor – also known as Sentinel-5P – is the first Copernicus mission dedicated to monitoring our atmosphere. The satellite carries the 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.
Given the growing importance and need for the continuous monitoring of air quality, the upcoming Copernicus Sentinel-4 and Sentinel-5 missions, as part of the EU’s Copernicus programme, will monitor key air quality trace gases and aerosols. These missions will provide information on air quality, stratospheric ozone and solar radiation, as well as climate monitoring.

Air pollution is a global environmental health problem that is responsible for millions of people dying prematurely every year. In cities and towns, traffic pumps pollutants such as nitrogen oxides and carbon monoxide directly into the air we breathe, which can increase the risk of cardiovascular and respiratory diseases, for example. Governments and decision-makers rely heavily on satellite data, such as that from the Copernicus Sentinel-5P mission, and computer models to show how pollution accumulates and how it is carried in the air so that they can develop appropriate mitigation strategies.
The United Nations World Health Organization marks World Health Day on 7 April every year. The third Sustainable Development Goal underlines the right to health: Ensure healthy lives and promote well-being for all at all ages. On-orbit research, space technology and space applications can help improve health on Earth by monitoring our environment, helping track disease, improving diagnostics, and working on new medicines among other things. The UN is also focusing particularly this year on universal health coverage.
