Drone for measuring data representative of amounts of at least two gases present in the atmosphere away from the ground and associated method

A drone for measuring data representative of amounts of at least two gases present in the atmosphere away from the ground, comprising:

• a chassis;
• at least one propeller configured to allow the chassis to move through the atmosphere, away from the ground;
• at least one representative data measuring sensor, the said at least one representative data measuring sensor being borne by the chassis;
• a controller configured to control the at least one representative data measuring sensor to measure the representative data, said controller being borne by the chassis, the at least one representative data measuring sensor being configured to measure data representative of amounts of at least two gases present in the atmosphere, the at least one representative data measuring sensor comprising at least one measurement cell that is open to the atmosphere, and, for the at least one measurement cell, at least a first laser source configured to inject, into the at least one measurement cell, a first laser beam at a first wavelength characteristic of a first gas to be detected and a second laser source configured to inject, into the same at least one measurement cell, a second laser beam at a second wavelength characteristic of a second gas to be detected, the at least one representative data measuring sensor comprising a detector common to the first and second laser sources, said common detector being configured to detect a first measurement signal originating from the at least one measurement cell and resulting from injection of the first laser beam into the at least one measurement cell and a second measurement signal originating from the at least one measurement cell and resulting from injection of the second laser beam into the at least one measurement cell.
