COMMENTS:
This aerosol lidar system is part of the EARLINET project (http://lidarb.dkrz.de/earlinet/). This system is able to provide independent measurements of the aerosol extinction and backscatter at 355 nm and backscatter measurements at 532 nm. Future upgrade: aerosol backscatter at 1064 nm and aerosol extinction at 532 nm.
