Comparison of nitrogen dioxide emissions over Europe between March/April 2019 and 2020
Comparison of nitrogen dioxide emissions over Europe between March/April 2019 and 2020
The Benelux countries, West Germany, Northern Italy, the southern United Kingdom, as well as hotspots like the Po Valley, Madrid, Paris, Milan and Rome show a decrease of tropospheric nitrogen dioxide of more than 40 percent compared to the previous year. The aforementioned weather-related fluctuations were reduced by the creation of monthly averages. These averages were calculated for the period 16 March to 15 April. No adjustment of the weather influence by the combination of long-term satellite observations, in-situ measurements and model calculations as described in the text was made.
