Abstract
An algorithm of software complex is developed to process data of lidar gas analysis in IR wavelength range for a horizontal path of atmospheric sensing. The complex comprises: the module of writing data from atmospheric lidar sensing, module of absorption cross-section calculation, and module of methane concentration profile retrieval. The software complex for processing lidar gas analysis data, developed on the basis of the created algorithm, makes it possible to obtain retrieved methane concentration profiles along 1 km sensing path from the set of recorded return signals. The modules for writing data from atmospheric lidar sensing and for retrieving methane concentration profiles allow for a visual control of recorded return signals and retrieved methane concentration profiles. We present an example of retrieving methane concentration profile from lidar data that is obtained in Tomsk.
