[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 time sources of atmospheric pollutants. The method comprises the following steps: acquiring emission concentrations of pollutants at different times in a timing duration, wherein the timing duration is time from a timing starting moment to a target moment; dividing the timing duration into N detection durations according to a preset steplength, and comparing N with M; if N is greater than M, determining the pollutant concentration contributed to the target detection duration by the emission concentration in the last M continuous detection durations in the N detection durations, wherein the target detection duration is the detection duration of the target moment, and the emission concentration in the Mth detection duration counted from the target detection duration according to the time from back to front is the accumulated value of the emission concentration in the first N-(M+1) detection durations in the timing duration; and if N is less than or equal to M, determining the pollutant concentration contributed by the emission concentration in the N detection durations to the target detection duration. Source analysis of atmospheric pollutants from different time sources is realized, and computing resources are saved.

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...
