Abstract

The invention discloses a novel estimation method for point source CO2 emission based on CO2-DIAL simulation measurement. The method comprises the following steps: inverting CO2 emission of a specific local point source by utilizing a Gaussian diffusion model and CO2 concentration of range analysis; and the method comprises the following steps: calculating and measuring the position of a differential absorption laser radar observation point; establishing a linearization equation by utilizing a Gaussian linear diffusion model; solving the equation by using a Jacobi iterative algorithm; and comparing the CO2 concentrations of the observation points calculated according to different heights of the chimney with the CO2 concentrations of the actually measured observation points, and when the error is minimum, determining the effective emission height of the strong point source so as to determine the CO2 emission intensity of the strong point source. The inversion method provided by the invention is combined with a ground-based CO2 differential absorption laser radar for use, so that the CO2 emission intensity of a point source can be obtained with high precision, and an important supplementary means is provided for artificial CO2 emission monitoring and verification.

Description

technical field [0001] The invention relates to the field of atmospheric remote sensing, in particular to a CO-based 2 -DIAL analog measurement of point source CO 2 A Novel Estimation Method for Emissions. Background technique [0002] CO emitted by human activities 2 is atmospheric CO 2 The main reason for the increase. Atmospheric CO over the past few centuries 2 The sharp increase has caused various impacts such as global warming and severe climate change. However, high-powered power plants account for more than 30% of anthropogenic emissions, and atmospheric CO 2 The increase in the content is mainly due to the CO produced by the burning of fossil fuels 2 caused by increased emissions. The United Nations Convention on Climate Change (UNFCCC) to control man-made carbon dioxide emissions. Monitor CO 2 Traditional approaches to emissions depend on emissions inventories. Although emissions inventories are highly accurate and reliable, their quality is highly depen...
