The use of airborne remote sensing methods to determine methane concentrations on the ground has become an alternative to traditional on-site observation methods. However, the use of aircraft as a carrier of a lidar system is not always economically justified. In this paper, a modeling of 3.3 μm differential absorption lidar systems is carried out, the technical characteristics of which allow an unmanned aerial vehicle to be used as a carrier. The possibility of determining methane concentrations in a wide range (from 2 to 75 ppm) is shown, and optimal conditions for using such a system are determined
