Abstract: There are many disadvantages in existing air quality prediction methods, wherein a first method requires a large amount of input parameter data and has extremely high requirements for computing resources and meteorological monitoring networks; and since a second method is based on historical meteorological data and historical air quality data, the second method requires the two types of data simultaneously, and this simple prediction method that is based on historical meteorological data and historical air quality data has a lower accuracy. The present solution provides an accurate and real-time prediction method for meso and micro scales, and can accurately predict the drifting movement direction and trajectory of pollution.
