Satellite-ground comprehensive monitoring quantitative remote sensing fusion processing method for atmospheric particulate matter

Abstract

The invention discloses a satellite-ground comprehensive monitoring quantitative remote sensing fusion processing method for atmospheric particulate matters. The method mainly comprises the following steps: a, analyzing types or components of dust-haze aerosol particulates; b, on the basis of dust-haze aerosol particulate feature observation data of the Beijing-Tianjin-Hebei region and prior knowledge, improving a remote sensing inversion model, acquiring dust-haze optical thickness inversion near-ground PM2.5 concentration distribution; c, combining the dust-haze optical thickness inversion near-ground PM2.5 concentration distribution, pollutant ground observation data, climate and environment auxiliary information and dust-haze aerosol particulate type or component analysis to form comprehensive ground dust-haze data; d, combining the comprehensive ground dust-haze data in the step c with atmospheric chemical or air quality modes and satellite remote sensing and ground observation multi-source data, and achieving short-term forecasting of dust-haze pollution distribution. The satellite-ground comprehensive monitoring quantitative remote sensing fusion processing method for the atmospheric particulate matters, which is disclosed by the invention, has the advantages that acquired dust-haze data are relatively precise and high in reliability.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to a quantitative remote sensing fusion processing method for satellite-terrestrial comprehensive monitoring of atmospheric particulate matter. Background technique [0002] With the rapid development of science and technology, our environment is also becoming increasingly depleted. Human health is closely related to the environment, and it is imperative to protect the environment. The acquisition of my country's environmental monitoring indicators mainly adopts the effective acquisition of sensors, and then uses various algorithms to obtain the special products of fusion information with high spatial resolution, high time resolution and high detection accuracy of environmental information. However, the fusion technology of environmental monitoring big data is still in the development stage, and the technology is not yet mature. In the face of a large amount of dat...
