Study on data quality control method of aerosol lidar data

Mie scattering lidar is a powerful technique for detection of atmospheric aerosol, it is a strong support and supplement to the conventional ground monitoring technology. Data quality control is the fundamental guarantee for business promotion and in-depth study. In order to construct the lidar operational observation network, the data quality control method of aerosol lidar must be discussed. From the basic principle of mie aerosol lidar, the core indicators for quality control data of distance accuracy calibration, channel gain ratio,single pulse energy, geometric overlap factor, baseline and data retrieval method were discussed in detail, this provides an effective reference for the establishment of data quality control method for Mie scattering lidar.
