Problems solved by technology

[0003] To carry out clean energy dispatching and operation, it is first necessary to understand the real situation of haze pollution and the subsequent change trend. At present, ground observation methods are mostly used to analyze the occurrence and movement of haze. However, due to scattered observations, the overall pollution trend cannot be grasped. difficulty

Embodiment 1

[0038] see figure 1 , the present embodiment provides a method for analyzing movement of smog based on satellite monitoring, comprising the following steps:

[0039] S1: Divide the area to be monitored into grids, select at least two adjacent grids to form a basic area, and form sub-areas according to the size of the basic area;

[0040] S2: Use satellites to monitor each grid at least twice within a set period of time, and calculate the aerosol optical depth value of each grid area at each monitoring moment;

[0041] S3: Construct the aerosol optical depth sequence of the basic region according to the aerosol optical thickness value in the grid of the basic region, and construct the aerosol optical depth of each subregion according to the aerosol optical thickness value in the grid of each subregion sequence, calculate the correlation between each sub-region and the basic region according to the aerosol optical depth sequence of the sub-region at the later monitoring time an...

Abstract

The invention relates to the field of power distribution technology, and discloses a method and system for analyzing smog movement based on satellite monitoring, so as to realize effective analysis of smog movement and quickly and accurately understand the pollution caused by smog; the method of the present invention Including: dividing the area to be monitored into grids, selecting at least two adjacent grids to form a basic area, and forming the remaining grids into sub-areas according to the size of the basic area; Perform at least two monitoring times for each grid area, and calculate the aerosol optical depth value of each grid area at each monitoring time; The thickness sequence calculates the correlation between each sub-area and the basic area, and obtains the sub-area with the greatest correlation with the basic area; further obtains the movement of haze in the area to be analyzed.

Description

technical field [0001] The invention relates to the field of power distribution technology, in particular to a method and system for analyzing smog movement based on satellite monitoring. Background technique [0002] In recent years, smog incidents have occurred frequently, and people's living and ecological environment have gradually deteriorated, seriously affecting people's production and life, as well as physical and mental health. With the continuous improvement of my country's power grid construction, electric energy is gradually replacing polluting energy such as coal as a clean energy, and can effectively improve air quality problems during periods of high smog. [0003] To carry out clean energy dispatching and operation, it is first necessary to understand the real situation of haze pollution and the subsequent change trend. At present, ground observation methods are mostly used to analyze the occurrence and movement of haze. However, due to scattered observations...
