Comparison of Sentinel-5P recordings of nitrogen dioxide emissions over Asia between 2019 and 2020
Comparison of Sentinel-5P recordings of nitrogen dioxide emissions over Asia between 2019 and 2020
The high-resolution data from Sentinel-5P also show a decrease in nitrogen dioxide over Asia of more than 40 percent in some cases, compared to the previous year. The decrease is not limited to large cities. Even Mumbai and Delhi in India show a decrease in the order of 40 to 60 percent compared to 2019. The above-mentioned weather-related fluctuations were reduced by creating monthly averages. An adjustment of the weather influence by the combination of long-term satellite observations, in-situ measurements and model calculations described in the text was not carried out here.
