Problems solved by technology

[0004] Due to the satellite orbit interval, cloud coverage and the limitations of the dark target inversion algorithm itself, the spatial coverage of remote sensing image inversion particulate matter products is low and there is a large-scale lack of data, which is difficult to be a good fusion data source. However, its application in air quality monitoring and other fields is limited

specific Embodiment

[0080] The implementation process of the remote sensing monitoring method for atmospheric particulate matter based on data fusion provided by the embodiment of the present invention will be described below in conjunction with a practical case:

[0081] 1. Inversion of satellite remote sensing data. The study used the MODIS satellite image data on May 5, 2016 to carry out aerosol remote sensing inversion, and used the boundary layer height and humidity to perform vertical correction and humidity correction. Determine the mass concentration of particulate matter near the ground, and obtain the PM2.5 remote sensing inversion monitoring map based on MODIS, as shown in figure 2 shown.

[0082] from figure 2 It can be seen that the white area is the space of missing data, so the spatial coverage of satellite remote sensing retrieval data is low, which is not conducive to accurate air quality forecasting.

[0083] 2. Integration of ground measured data and satellite remote sensi...

Abstract

The invention discloses a data fusion-based atmosphere particulate matter remote sensing monitoring method, and relates to the technical field of air quality monitoring. According to the method, particulate matter concentration data of complete coverage space are obtained by fusing satellite remote sensing inversion data and ground surface monitoring data and performing interpolation operation on a fused result, so that the problem of particulate matter concentration data deficiency caused by weather, a satellite orbit interval, a cloud cover problem and the limitation of a dim target inversion algorithm is effectively solved, and the accuracy rate of air quality monitoring is greatly improved.

Description

technical field [0001] The invention relates to the technical field of air quality monitoring, in particular to a remote sensing monitoring method for atmospheric particles based on data fusion. Background technique [0002] The main purpose of data fusion is to extract more and more valuable information from multi-source data than the original single-source data, and to improve and improve the performance indicators of the original data in some aspects. For remote sensing monitoring of particulate matter, the purpose of fusion is to maximize the spatial coverage of particulate matter data on the basis of ensuring its original spatial resolution, and provide timely and effective particulate matter products for air quality research. [0003] At present, data fusion is mainly carried out by using MODIS, HJ, FY and other image retrieval data obtained from remote sensing monitoring of atmospheric particulate matter. However, this data fusion method has the following defects: ...
