Remote-sensing measuring and calculating method and device for total amount of haze in atmosphere

Abstract

The invention provides a remote-sensing measuring and calculating method and device for the total amount of haze in the atmosphere. The remote-sensing measuring and calculating method comprises the steps of acquiring a satellite observation image of a selected haze pollution region; recognizing the haze region in the satellite observation image according to observed target recognition criteria corresponding to different wavebands of satellites, wherein the observed target recognition criteria at least comprise haze recognition criteria; and determining the total amount of haze in the selected haze pollution region according to the haze intensity, the haze region area, the haze thickness and a vertical distribution profile of the haze in the haze region. According to the invention, the haze pollution region can be recognized in real time according to the observed target recognition criteria corresponding to different wavebands of the satellites, the total amount of the haze is further calculated, vertical space structure detection for a haze pollution layer, whole layer thickness detection for the haze pollution and spatial distribution monitoring for the haze pollution are realized, frequently occurring regional haze pollution can be monitored in a quantitative manner, and the monitoring result is high in accuracy.

Description

technical field [0001] The invention relates to the technical field of atmospheric remote sensing pollution detection, in particular to a method and device for remote sensing measurement and calculation of the total amount of haze in the atmosphere. Background technique [0002] Haze is a cloudy phenomenon in which a large number of particulate pollutants accumulate in the atmosphere, causing reduced visibility. In recent years, in the process of sustained and rapid economic development, factors such as industrial activities and a sharp increase in motor vehicles have continuously exacerbated the deterioration of my country's air quality, and the large-scale emissions of high-concentration atmospheric particulate matter and its precursors have caused serious regional pollution. In recent years, haze pollution has occurred frequently in North China, where cities and villages are densely populated, and the haze usually stretches over hundreds of thousands of square kilometers,...

Problems solved by technology

[0004] Due to the complex aerosol characteristics and emission and diffusion characteristics in my country, there are many uncertainties in traditional ground station monitoring

Since haze pollution layers are likely to be non-uniformly distributed both vertically and horizontally, a limited number of ground stations cannot well characterize the distribution of pollution over a large area, and single-point sampling is likely to overestimate the contribution of nearby sources, monitoring representative Poor sex

It is difficult to monitor the large-scale characteristics of frequent regional pollution, such as the distribution range, change process, and total amount of pollution, by only relying on ground station monitoring.
