Tracking nitrogen dioxide across the globe
Today’s Video of the Day from the European Space Agency features the work of the Copernicus Sentinel-5P satellite, which was launched in 2017 to map air pollutants such as nitrogen dioxide (NO2).
Transportation and industry are two of the biggest contributors of NO2 emissions. Nitrogen dioxide pollution can have a significant impact on human health, and is known to cause respiratory and cardiopulmonary issues.
The Copernicus Sentinel-5P satellite is equipped with an instrument called Tropomi that can image air pollutants with unprecedented accuracy and spatial resolution.
Folkert Boersma is an associate professor at Wageningen University and a research scientist at the Royal Netherlands Meteorological Institute (KNMI). “The spatial resolution of the satellite is so good, that we can pinpoint emissions in fine detail and also detect gradients of emissions in large cities,” said Professor Boersma.
