Inversion method, device and equipment of carbon dioxide emission and storage medium

Abstract

The invention provides an inversion method, device and equipment of carbon dioxide emission, and a storage medium. The method comprises the following steps: acquiring a CO2 simulation concentration of a target area in a specified time period; based on the prior CO2 emission amount of the target area, and the CO2 monitoring data, the CO2 background data and the CO2 simulation concentration of the target area in the specified time period, the CO2 simulation emission amount is determined; respectively inputting the plurality of first priori emission amount error covariances, the priori CO2 emission amount and an error covariance of a preset atmospheric transmission model into a Bayesian inversion model, and performing inversion to obtain a plurality of first CO2 emission amounts; determining a first prior emission amount error covariance corresponding to the first CO2 emission amount with the minimum difference with the simulated CO2 emission amount as an optimal prior emission amount error covariance; and finally, performing inversion to obtain the carbon dioxide emission of the target area in a specified time period. According to the method, the inversion result is more accurate by reducing the influence of the prior emission load error covariance.

Description

technical field [0001] The invention relates to the field of atmospheric technology, in particular to a method, device, equipment and storage medium for inversion of carbon dioxide emissions. Background technique [0002] The increase in atmospheric carbon dioxide concentration caused by human activities leads to global climate change, which brings a huge threat to the survival and development of human society. Additional measures must be taken to limit carbon dioxide emissions. [0003] In recent years, with the conclusion of the "Paris Climate Agreement", the world is accelerating towards the goal of carbon neutrality. At present, there are a series of direct or indirect estimation methods in the world, all of which are based on data assimilation techniques combined with atmospheric transport models and CO 2 Ground station observation data, inversion to obtain surface CO 2 emissions. [0004] However, there are many uncertain factors in the process of atmospheric carbon ...
