Almost all of continental Europe is under persistent atmospheric high pressure. In addition to causing record barometric pressure values in Denmark, it has also negatively affected air quality, due to the reduced atmospheric circulation.
In fact, as shown in this visualisation of the nitrogen dioxide (NO₂) measurements acquired on 22 March 2022 by the Copernicus Sentinel-5P satellite, the concentration values diffusely reached 0.1 mmol/m² over Northern Italy, Germany, Northern France, Belgium, the Czech Republic, Hungary, the Netherlands, Poland and Denmark. These values are comparable with the values measured by the Copernicus Sentinel-5P satellite in March 2021 and confirm the trend of a return to pre-pandemic levels of NO₂ pollution.
