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...
