The confinement due to the Covid-19 crisis led to an improvement in air quality.

Summary

[edit]
Description
English: The confinement due to the Covid-19 crisis led to an improvement in air quality. Looking at the data captured by the Copernicus Sentinel-5P satellite, the decrease of atmospheric pollutants such as nitrogen dioxide (NO2) over the areas where confinement measures have been put in place is evident. This image, obtained using the measurements taken by the Copernicus Sentinel-5P satellite, compares the monthly average of NO2 of April 2019 and April 2020. Looking at the image, we can note a significant decrease of NO2 in most urbanised areas of the European Union: -39% over Paris, -36% over Brussels, -40% over Milan. The Copernicus Sentinel-5P satellite delivers key information on aerosols and trace gases such as sulfur dioxide, carbon monoxide and others.
