Problems solved by technology

[0003] It can be seen that the process of compiling the emission source inventory requires a lot of investigation work, so it is time-consuming and laborious, and the compilation cycle is long.
When actually applied to air quality forecasting, changes in pollution source emissions due to industrial adjustments may not be reflected in the emission source inventory data in a timely manner, affecting the accuracy of forecasting

Embodiment Construction

[0035] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0036] The present invention provides an air quality forecasting scheme based on dynamic inversion of emission source data. The basic idea is to further define and measure the air quality The objective function of the difference between the monitoring data Co and the air quality forecast data C is to invert the emission source data that minimizes the objective function J; use the emission source data S obtained from the inversion 1 Carry out the air quality forecast calculation again to obtain accurate air quality forecast results.

[0037] Since the air quality monitoring data Co used to invert emission source data also has errors, and the distribution of monitoring stations is uneven, the air quality monitoring data only partially reflect the temporal and spatial distribution information of atmospheric pollutant concentrations. If the emission source da...

Abstract

The invention discloses an air quality forecasting system based on dynamic inversion emission source data, which utilizes multiple means to dynamically update the emission source data and improves theair quality forecasting accuracy. In the system, for an emission source provided with flue gas online monitoring equipment, emission source data Sa are calculated through emission parameters, and thedata of Sa are not adjusted during inversion; the content in the emission source data Sb generated based on the emission source list is replaced with the data in the Sa to generate emission source data Sc; the air quality forecasting unit obtains air quality forecasting data by utilizing the emission source data Sc; an emission source data inversion unit inverts emission source data S1 enabling the difference between the air quality prediction data and the monitoring data to be minimum; and the combination unit combines the emission source data before and after inversion for the emission source without the flue gas online monitoring equipment to obtain final emission source data Sfinal, and feeds back the final emission source data Sfinal to the emission source data inversion unit to generate a final air quality prediction result.

Description

technical field [0001] The invention belongs to the technical field of air quality forecasting, in particular to an air quality forecasting system based on dynamic inversion of emission source data. Background technique [0002] Air quality numerical forecasting is a method of forecasting air quality based on emission source inventory, meteorological field forecast data, and environmental monitoring data, using air quality forecasting numerical models to simulate the distribution and evolution of atmospheric pollutants in the future. The emission source inventory data used in the current air quality forecasting technology is based on the investigation and data processing of pollution sources. The compilation of the emission source inventory is based on the corresponding regulations, norms and technical methods, conducts a preliminary investigation of the emission sources in the area where the inventory is compiled, clarifies the main components of the local emission sources,...
