Nitrogen oxides and particulates over Asia: HALO research aircraft measures the emissions of megacities


Air quality in major cities is a hot topic, especially with regard to road traffic and residents' health. However, emissions do not just remain in conurbations. Instead, particles and gaseous pollutants can often be transported thousands of kilometres by the wind. This scenario is particularly relevant in Asia, home to the world's largest concentration of megacities. From 10 March to 9 April 2018, the German Aerospace Centre (Deutsches Zentrum fuer Luft- und Raumfahrt; DLR) is conducting research flights from Tainan in Taiwan, in order to more closely examine the spread and transformation of emissions from major cities, such as Manila, Taipei, Seoul, Tokyo, Beijing, Shanghai and Guangzhou. The University of Bremen is the scientific base of the international project known as EMeRGe (Effect of Megacities on the transport and transformation of pollutants on the Regional and Global scales). The aim is to better understand and predict the extent and impact of urban air pollution on Earth's atmosphere. Previously, the researchers studied European conurbations from the air.
