Aerosol lidar intercomparison in the framework of the EARLINET project: 3. Raman lidar algorithm for aerosol extinction, backscatter and lidar ratio.

An intercomparison of the algorithms used to retrieve aerosol extinction and backscatter starting from Raman lidar signals has been performed by 11 groups of lidar scientists involved in the European Aerosol Research Lidar Network EARLINET . This intercomparison is part of an extended quality assura...

This intercomparison is part of an extended quality assurance program performed on aerosol lidars in the EARLINET. Lidar instruments and aerosol backscatter algorithms were tested separately.
