Title:
INVERSION METHOD AND APPARATUS FOR CARBON DIOXIDE EMISSION, AND DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/206984
Kind Code:
A1
Abstract:
An inversion method and apparatus for a carbon dioxide emission, and a device and a storage medium. The method comprises: acquiring a CO2 simulated concentration of a target area within a specified time period (S110); on the basis of an a priori CO2 emission of the target area, and CO2 monitoring data, CO2 background data and the CO2 simulated concentration of the target area within the specified time period, determining a CO2 simulated emission (S120); respectively inputting into a Bayesian inversion model a plurality of first a priori emission error covariances, the a priori CO2 emission, and an error covariance of a preset atmospheric propagation model, and performing inversion to obtain a plurality of first CO2 emissions (S130); determining to be an optimal a priori emission error covariance the first a priori emission error covariance corresponding to the first CO2 emission having the minimum difference with the CO2 simulated emission (S140); and finally, performing inversion to obtain a carbon dioxide emission of the target area within the specified time period (S150). By means of the method, the influence of an a priori emission error covariance is reduced, such that an inversion result is more accurate.
