Embodiment

[0037] Atmospheric CO is retrieved using forward modeling and optimal estimation using the Atmospheric Radiative Transfer Model (VLIDORT) 2 The specific technical route such as figure 1 Shown; In the calculation of short-wave infrared remote sensing retrieval of carbon dioxide under cirrus atmospheric conditions, parameters such as the scattering phase function, extinction efficiency factor, and single scattering albedo of ice crystal particles need to be input. The light scattering characteristic parameters of ice crystal particles adopt the database established by Yang et al. The ice crystal particles are respectively solid prism model (Solid Column, COL), solid prism polymer model (Aggregate Solid Column, ASC) and general species mixture model (General Habit Mixture ,GHM); Table 1 gives the extinction efficiency factor, single scattering albedo and asymmetry factor parameters of ice crystal particles at different wavelengths;

Abstract

The invention discloses a method for short wave infrared satellite remote sensing of carbon dioxide in the presence of cirrus cloud and relates to the field of atmosphere constituent detection. The method solves the problem that the concentration of carbon dioxide in the atmosphere can not be detected precisely in the presence of cirrus cloud. The method comprises the steps of 1, conducting dimensionality reduction and denoising pretreatment on hyperspectral remote sensing data; 2, building a short wave infrared hyperspectral remote sensing forward modeling radiation transfer model, wherein the radiation transfer and scattering properties of cirrus cloud short wave infrared ray are calculated and straightforward calculation of short wave infrared ray is conducted under the condition of a clear sky and in the presence of cirrus cloud; 3, building a carbon dioxide inversion model and a calculation method in the presence of cirrus cloud. By the adoption of the method, the concentration of carbon dioxide in the atmosphere can be detected precisely in the presence of cirrus cloud.

Description

technical field [0001] The invention relates to the field of atmospheric component detection, in particular to a method for remote sensing carbon dioxide by a short-wave infrared satellite under the condition of cirrus clouds. Background technique [0002] Atmospheric CO 2 Natural changes in concentration and changes caused by human activities have a great impact on the study of atmospheric CO 2 Climate effects and global climate change are of great significance. High-precision measurement of CO 2 Concentration plays an important role in the study of the global carbon cycle. [0003] At present, atmospheric CO 2 Concentration data mainly rely on direct instrumental observations made by joint sampling and detection networks distributed in different parts of the world. In recent years, although a large number of direct instrumental observations of CO 2 Concentration data, but due to the high cost of observation, the distribution of stations is less, the spatial resolution...
