Dynamic Community Detection in China. a Spatial mapping of dynamic communities: The four dynamic communities align geographically with megacities and large industrial complexes. b Frequency of occurrence and size evolution of dynamic communities: The southeastern community (blue) is the least persistent due to the lower PM concentrations in that region. c Methodology illustration during five weeks of 2017, displaying the key events of community evolution tracking. d Dynamic communities’ core nodes may sufficiently reproduce the key spatiotemporal patterns of the analysis
