[0050] With the rapid economic development, urban air pollution is becoming more and more serious. Air pollution is affected by the interaction of a series of complex physical and chemical processes. These influencing factors include: pollution source emissions, meteorological conditions, chemical reactions, and sedimentation. Therefore, forecasting air quality requires a reasonable des...

Abstract

The invention provides a method and a device for determining the time source of air pollutants. The method obtains the emission concentration of pollutants at different times within the timing duration. The timing duration is the time from the timing start time to the target time. According to the preset step length, the timing duration is divided into N detection durations, and the N and M Size; if N is greater than M, determine the pollutant concentration contributed by the emission concentration in the last M detection durations within N detection durations to the target detection duration, and the target detection duration is the detection duration at the target moment, starting from the target detection The duration starts from the back to the front, and the emission concentration in the Mth detection duration is the cumulative value of the emission concentration in the first N-M+1 detection durations within the timing duration; if N is less than or equal to M, determine N detection durations The pollutant concentration contributed by the emission concentration within the target detection time. The source apportionment of air pollutants from different time sources is realized, saving computing resources.

Description

technical field [0001] The invention relates to the technical field of atmospheric environment, in particular to a method and device for determining the time source of atmospheric pollutants. Background technique [0002] Atmospheric pollution is affected by the interaction of a series of complex physical and chemical processes, including: pollution source emissions, meteorological conditions, chemical reactions, deposition, etc. Therefore, forecasting air quality requires a reasonable description of the above factors. Calculating the sources of pollutant concentrations is of great significance for comprehensive pollution control planning. [0003] In the prior art, for pollution sources in different regions, an air quality source analysis model can be used for source analysis to determine the contribution of pollutant concentrations in different regions. The Nested Grid Air Quality Prediction Model (NAQPMS) is the third-generation air quality model designed based on the c...
