Simulation of tropospheric methane concentration measurements by airborne differential absorption lidar
The results of computer simulation of the overlap function for a biaxial scheme of an airborne lidar with different radii of the photosensitive zone of the receiving part of the optical system are presented. It is shown at what sizes of the photosensitive zone the full overlap of the field of view of the telescope and the laser beam is ensured, the length of the "dead" zone is estimated when the laser beam propagates parallel relative to the optical axis of the telescope. Numerical modeling of methane sounding for the atmospheric conditions of summer in the middle latitudes and the Arctic has been carried out. The simulation results show the possibility of measuring the spatial distribution and integral content of methane on vertical tropospheric paths using an upgraded airborne lidar.
