Kurzfassung
Megacities exert substantial demands on the world's energy resources, thereby producing large shares of atmospheric emissions and air pollution. Despite several studies on nitrogen dioxide (NO2) changes in megacities, a systematic analysis in relation to settlement growth is still pending. This study examines the trends of tropospheric NO2 pollution in 38 megacities regarding settlement growth by analyzing Earth Observation data. Multiannual records of tropospheric NO2 from Global Ozone Monitoring Experiment (GOME), Scanning Imaging Absorption Spectrometer for Atmospheric Chartography, GOME-2A, and GOME-2B are evaluated regarding the World Settlement Footprint evolution from 1996 to 2015. Compared to previous studies, this work strictly uses remote sensing data and the spatial concept of functional urban areas. Therefore, uncertainties due to inconsistent spatial references, incomparable administrative units, as well as heterogeneously reported local data are widely excluded to enable an appropriate comparison of megacities across the globe. On average, we observe an increase in tropospheric NO 2 burden of 5.06 ± 0.83%/year and a relative settlement growth of 2.87%/year for the time period considered. We find a wide range of trends: relative NO2 pollution ranges from an increase of 44.0 ± 5.9%/year to a decrease of −3.2 ± 0.2%/year, settlement growth rates vary from 0.3%/year to 9.5%/year. Despite this variety, the results exhibit a pronounced relation to the income group following the world's economies classification of the World Bank. Complemented by a cluster analysis and ranking of the megacities, the study provides indicators to develop a better understanding of the drivers and impacts of urbanization and air pollution.
