Abstract The concentration distribution of fine particulate matter (PM_2.5) on the surface of the atmosphere has a strong temporal and spatial heterogeneity. Due to the limited spatial coverage of traditional PM_2.5 monitoring sites, it is difficult to reflect the complexity of PM_2.5 concentration in time and space. This paper proposed a temporal and spatial prediction model of ground PM_2.5 concentration based on deep learning methods(PM_2.5-DNN). Based on the AOD data from Kuihua-8satellite and the observation data from PM_2.5 monitoring and meteorological station, hourly high-precision simulations of the surface PM_2.5 concentration in Beijing had been carried out. The results show that the 1km resolution hourly ground PM_2.5 concentration in Beijing area estimated by the PM_2.5-DNN model had good consistency with the observation data from the surface monitoring station. The model estimation accuracy could reach R²=0.88, which was better than the performance of current mainstream method. The method proposed in this paper was suitable for fine-grained modelling and estimation of the temporal and spatial distribution of PM_2.5 concentration at a regional scale. The end-to-end training method is used to construct the model, which provides a simple and effective method model for fine PM_2.5 concentration estimation.
