Thanks to a current study with significant participation of the Helmholtz-Zentrum Hereon, the distribution of particulate matter in cities can be calculated more precisely. Within the framework of the United Nations (UN) Sustainable Development Goals (SDGs), the indicator 11.6.2 for capturing exposure to particulate matter in cities can be calculated in greater detail. The advantages are the more precise determination of the indicator and the possibility of uniform application throughout Europe. Using Hamburg as an example, the study shows different levels of pollution according to districts, neighborhoods and even blocks. The study was recently published in the journal Remote Sensing.
