摘要：
In the present work, systematic errors of lidar gas analysis in the atmosphere by the differential absorption lidar method in the near- and middle-IR ranges of the spectrum are analyzed. It is demonstrated that the systematic errors depend on many factors, including the meteorological parameters and concentrations of the examined gases along the sensing path, instability of the spectral parameters of laser radiation lines, shift of the absorption line centers caused by the air pressure, Doppler broadening of backscattered signals, and other sources of errors. Methods of error minimization in reconstructing lidar profiles of the examined atmospheric gas concentrations are suggested.
