Abstract
Convolutional Neural Network (CNN) is one of the main deep learning algorithms that has gained increasing popularity in a variety of domains across the globe. In this paper, we use U-net, one of the CNN architectures, to predict spatial PM2.5 concentrations for each 500 m × 500 m grid in Beijing. Different aspects of data including satellite data, meteorological data, high density PM2.5 monitoring data and topography data were taken into consideration. The temporal and spatial distribution patterns of PM2.5 concentrations can be learned from the result. Then, a customized threshold was added for each predicted grid PM2.5 concentration to define high-value areas to find precise location of potential PM2.5 discharge events.
