Abstract

The invention discloses an atmospheric pollution component inversion method based on the ultraviolet-visible hyperspectrum of a Gaofen-5 satellite, which can accurately obtain the column concentrationof atmospheric pollution components by performing inversion calculation on the ultraviolet-visible hyperspectrum of the Gaofen-5 satellite so as to realize large-range long-time continuous and effective observation of the atmospheric pollution components. Moreover, secondary spectrum calibration under the conditions of low spectrum signal-to-noise ratio and poor stability can be realized according to the characteristics and spectral characteristics of the Gaofen-5 instrument, so the inversion precision is improved.

Description

technical field [0001] The invention relates to the technical field of remote sensing monitoring of air quality, in particular to an air pollution component inversion method based on the high-visible ultraviolet-visible hyperspectral spectrum of the Gaofen-5 satellite. Background technique [0002] Accurate monitoring of air pollution is an important prerequisite for the control and treatment of pollution problems. The existing routine air pollution monitoring of the ecological environment department relies on ground-based chemical in-situ detection, ground-based optical remote sensing observation and other means, which cannot achieve continuous and effective observation in a large area for a long time. Satellite observations can usually achieve large-scale global observations, which have advantages that ground monitoring cannot match. However, due to complex space conditions such as cosmic ray radiation, oxygen atoms, and ultraviolet exposure, the spectral quality and prod...
