Embodiment Construction

[0044] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0045] like figure 1As shown, the point source carbon emission flux measurement method based on mobile FTIR remote sensing of the present invention uses a closed-loop navigation observation vehicle platform to measure the greenhouse gas carbon emission flux in the power plant area. It uses a vehicle-mounted FTIR spectrometer, and obtains the solar absorption spectrum in the power plant area based on the on-board FTIR spectrometer, and uses the nonlinear least squares inversion algorithm to achieve the greenhouse gas column concentration inversion. Among them, the c...

Abstract

The invention discloses a point source carbon emission flux measuring and calculating method based on mobile FTIR remote sensing, which comprises the following steps: carrying out closed-loop underway observation on the concentration of a point source greenhouse gas column by using a mobile FTIR, accurately tracking a solar spectrum in the traveling process of a vehicle based on a foundation FTIR arranged on the vehicle, and calculating the carbon emission flux of the point source. It is ensured that the FTIR spectrometer can still continuously record solar spectrum data when the system is in a motion state; based on a specific spectrum screening and correction pretreatment method, spectrums which are seriously influenced by interference or have a poor fitting effect are eliminated so as to control the quality of the spectrums. The method comprises the following steps: inverting the concentration of a greenhouse gas column based on a nonlinear least square fitting algorithm to obtain the concentration distribution of the greenhouse gas column around a point source; point source greenhouse gas emission flux calculation is performed on the basis of a greenhouse gas concentration result measured by foundation FTIR winding in combination with wind speed and wind direction information, and flux calculation errors are analyzed.

Description

technical field [0001] The invention belongs to the technical field of environmental monitoring, and in particular relates to a point source carbon emission flux measurement method based on mobile FTIR remote sensing. Background technique [0002] At present, most of the CO2 and CH4 monitoring stations established in China are located in mountains, islands and coasts, and relatively few monitoring studies with high temporal resolution have been carried out in urban areas. Moreover, the current domestic monitoring of regional emissions of power plants mainly adopts the bottom-up calculation method, using emission factors and statistical data such as coal and power equipment operating conditions to calculate the greenhouse gas emissions of power plants. However, the greenhouse gas measurement method based on emission factors has a large error, and it is difficult to clarify the variation characteristics of greenhouse gas emissions in the power plant area, resulting in deviat...
