AI Technical Summary

Technical Problem

Existing methods for measuring greenhouse gas emissions from sources, such as plumes, are inaccurate due to difficulties in positioning measurement systems correctly and accounting for wind direction and plume extent, leading to incomplete flux measurements.

Method used

A method involving a drone with a data measurement set that adjusts its flight plan dynamically based on real-time gas concentration data, extending or modifying measurement segments to ensure complete coverage of the plume, and correcting for wind direction inconsistencies.

Benefits of technology

This approach enhances the accuracy of gas flux measurements by ensuring comprehensive coverage of the plume and accounting for wind variations, resulting in more precise emission quantification.

Abstract

Method for measuring the content of at least one gas emitted by a source in a plume propagating in the atmosphere from the source, method, and associated drone. This method comprises the following steps: - defining an initial flight plan of a drone (22) along an initial measurement surface comprising a plurality of initial measurement segments; - flying the drone (22) along the initial flight plan and measuring representative content data on at least one initial measurement segment; - during the implementation of the initial flight plan and / or after the implementation of the initial flight plan, generating a modified flight plan from the representative content data measured during at least one initial measurement segment, the modified flight plan comprising a plurality of modified measurement segments defining a modified measurement surface; - measuring representative content data on the plurality of modified measurement segments of the modified measurement surface.Figure for the abbreviation: Figure 3.
