Abstract

With the increasing demand for visibility observations in fields such as wind power generation, meteorological observation, and civil aviation safety, the development of laser lidar for visibility monitoring based on the principle of backscattering has been realized. This paper uses the raw signal data obtained from the laser lidar as the basic data source, and, based on signal preprocessing, constructs a visibility retrieval model to achieve accurate extraction of visibility information. The laser lidar integrated with this visibility extraction method was tested in typical regions. The test results indicate that the visibility extraction method based on laser lidar achieved good results, showing a distribution consistent with the visibility measurement results of traditional visibility instruments, presenting a linear correlation with a correlation coefficient above 0.96, thereby enhancing the reliability of visibility products retrieved using laser lidar.
