Embodiment Construction

[0031] In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments. It may be evident, however, that these embodiments may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing one or more embodiments.

[0032] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0033] Since the high-concentration composite air pollution in China is special, the present invention evaluates the effect of aerosol scattering on CO in China. 2 The impact of remote sensing detection accuracy can be understood in the same way for other regions. The composition of aerosols in China is very complex, and parameters such as aerosol optical thickness, particle spectrum distribution, aerosol vertical distribut...

Abstract

The invention provides a method and system for assessing influence of aerosol scattering on the CO2 remote sensing detection precision. The method includes: establishing an aerosol particle scattering parameter database, an aerosol mode data set, a CO2 parameter database, and a forward direction radiation transfer calculation model; and determining the error of the CO2 remote sensing detection precision due to aerosol scattering in a region to be assessed according to the established aerosol particle scattering parameter database, the established aerosol mode data set, the established CO2 parameter database, and the established forward direction radiation transfer calculation model. The method and the system can accurately assess the influence of aerosol scattering on the CO2 remote sensing detection precision.

Description

technical field [0001] The present invention relates to near-infrared CO 2 The field of remote sensing detection, more specifically, relates to a method for evaluating the impact of aerosol scattering on near-infrared CO 2 A method and system for detecting the impact of remote sensing accuracy. Background technique [0002] With the rapid development of remote sensing detection technology in recent years, due to its advantages of continuous monitoring on a large spatial scale, it can make up for the lack of ground station monitoring on a spatial scale. Compared with conventional ground-based monitoring methods, remote sensing detection technology is more objective and has broad application prospects. [0003] At present, in atmospheric remote sensing detection technology, many gases (such as CO 2 、CH 4 , NO 2 and SO 2 etc.), the detection channels are selected in the short-wave near-infrared band range, but in the short-wave near-infrared band range, the interference o...
