Embodiment Construction

[0024] The specific embodiments of the present invention will be described in further detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.

[0025] Such as figure 1 As shown, according to one aspect of the present invention, a PM2.5 monitoring method based on Cubesat satellites is provided. The method includes: Step 1, using a preset imaging system carried by the Cubesat satellites to record the laser launch platform launching to the outer space The scattered light of the laser is used to obtain the target image; step 2, every first preset time interval, the target image is sent to the ground analysis device so that the ground analysis device obtains the PM2.5 concentration value according to the target image And distribution.

[0026] In this embodiment, a laser transmitter, such as a space-based laser transmitter, is provided on the laser emitting p...

Abstract

The invention provides a PM2.5 monitoring method and device. The method includes the steps that an imaging system carried by a preset Cubesat satellite is used for recording scattered light of lasersemitted by a laser emission platform to the outer space, target images are obtained and sent to a ground analysis device every first preset time, so that the ground analysis device obtains the concentration value and distribution of PM2.5 according to the target images, PM2.5 in a target space is observed in all directions on the premise that the atmospheric composition of the target space is notdestructed, and the concentration value and distribution of PM2.5 in the target space are obtained on the basis of the images observed in all directions. PM2.5 distribution obtained through observation of the target space in all directions is more accurate than PM2.5 distribution obtained through inversion of a satellite remote sensing monitoring method and PM2.5 distribution obtained through single-angle observation of a laser radar monitoring method, and the obtained PM2.5 concentration value is more accurate as well.

Description

Technical field [0001] The present invention relates to the technical field of satellite design, and more specifically, to a method and device for monitoring PM2.5 based on Cubesat satellites. Background technique [0002] PM2.5 refers to particulate matter with an aerodynamic equivalent diameter of 2.5 microns or less in ambient air. It has small particle size, large area, strong activity, easy to carry toxic and harmful substances (for example, heavy metals, microorganisms, etc.), and has a long residence time in the atmosphere and long transportation distance, which has a great impact on human health and atmospheric environmental quality. . Therefore, monitoring the concentration of PM2.5 is of great significance for air quality monitoring and the formulation of air quality improvement measures. [0003] In the prior art, methods for monitoring the concentration of PM2.5 mainly include: ground monitoring station monitoring method, satellite remote sensing monitoring method, an...
