Air pollution is a global environmental health problem, especially for those living in urban areas. Not only does it negatively impact our ecosystems, it considerably affects our health. According to the World Health Organization (WHO), around 8 million premature deaths per year are linked to air pollution, more than double of previous estimates.
One of the pollutants with the strongest evidence of health effects is nitrogen dioxide. In the EU, the largest contributor to nitrogen dioxide emissions is the road transport sector, as well as pollution produced from industrial activities, and residential combustion.
Air - Quality - Europe - Report - European
According to the Air quality in Europe report published in 2018 by the European Environment Agency (EEA), nineteen of the EU Member States recorded nitrogen dioxide concentrations above the annual limit value.
Not only is nitrogen dioxide damaging the ecosystem, it also causes significant health issues contributing to respiratory problems ranging from causing cardiopulmonary ailments, to exacerbating asthma and even impacting cognitive abilities.
Air - Quality - Concern - Copernicus - Sentinel-5P
With air quality increasingly becoming a serious concern, the Copernicus Sentinel-5P satellite was launched in 2017 to map a multitude of air pollutants around the globe. With its state-of-the-art instrument, Tropomi, it is able to detect atmospheric gases to image air pollutants more accurately and at a higher spatial resolution than ever before from space.
Folkert Boersma, Associate Professor at Wageningen University and Research Scientist from the Royal Netherlands Meteorological Institute (KNMI), comments, "The spatial resolution of the satellite is so good, that we...
