Higher-order Network Analysis of Fine Particulate Matter (PM _2.5) Transport in China at City Level.

ABSTRACT: Specification of PM _2.5 transmission characteristics is important for pollution control and policymaking. We apply higher-order organization of complex networks to identify major potential PM _2.5 contributors and PM _2.5 transport pathways of a network of 189 cities in China. The network we create in this paper consists of major cities in China and contains information on meteorological conditions of wind speed and wind direction, data on geographic distance, mountains, and PM _2.5 concentrations. We aim to reveal PM _2.5 mobility between cities in China. Two major conclusions are revealed through motif analysis of complex networks. First, major potential PM _2.5 pollution contributors are identified for each cluster by one moti
