Embodiment Construction

[0028] Pollution transport mainly refers to the continuous input process of pollutants brought by peripheral pollution sources to the monitoring area under the action of a specific wind field. Monitoring the pollution transport process is conducive to the study of the sources and pathways of pollutants, and can provide effective data support for the introduction of pollution prevention and control measures.

[0029] The algorithm flow of calculating pollutant transport flux using MAX-DOAS results is as follows: figure 1 , the vertical column concentration of pollutants in the troposphere can be obtained by using the DOAS algorithm combined with the measurement spectrum, and then combined with the wind field information, the flux calculation formula can be used to calculate the pollutant transport intensity, and the wind frequency and other information can be used to estimate the pollutant transport within a period of time. quantity.

[0030] Based on the regional distribution...

Abstract

The invention discloses a pollutant transport flux measurement and calculation method based on ground-based MAX-DOAS. The method comprises the steps: observing by using the ground-based MAX-DOAS to obtain the slant column density of polluted gas, and transforming into the vertical column density; obtaining a high-resolution two-dimensional distribution result of the polluted gas on an observation interface by using a satellite data result; using wind direction, wind speed information and an MAX-DOAS site location, determining a transport interface passing through an MAX-DOAS site, combining with a satellite data gridding result, and fitting to obtain a distribution curve of the polluted gas density along the interface; correcting satellite data by using the MAX-DOAS measurement result, to obtain a density distribution curve based on the ground-based MAX-DOAS vertical column density result; and finally, using a flux calculation formula, combining with relevant parameters, and calculating to obtain the transport flux of the polluted gas. The observation and measurement method is simple, apparatuses are easy to implement, the cost is low and the algorithm is mature.

Description

technical field [0001] The invention relates to the field of measurement and flux calculation of the vertical column concentration of polluting gases in the ambient atmosphere, in particular to a method for measuring and calculating the transport flux of pollutants based on ground-based MAX-DOAS. Background technique [0002] Since the 1980s, my country's social and economic development has entered a stage of rapid development, and in just over 20 years, it has completed the development of developed countries that took hundreds of years. Due to the rapid development of society and economy, the problem of atmospheric environmental pollution is becoming more and more serious. As a result, environmental problems that should have occurred at different stages have been concentrated and erupted in a short period of time. new features. [0003] At present, my country has established an automatic air quality monitoring station centered on the city, and established some ground-based...
