Paper Abstract

The ceilometer LD-40 manufactured by Jenoptik Impulsphysik is an eye-safe lidar system measuring continuously under all possible climatic conditions and scanning the atmosphere up to the tropopause. It uses laser diodes with 855 nm wavelength that are pulsed at an average frequency of 4000 Hz. During the summer of 1998 the Meteorological Observatory Lindenberg run by the German Weather Service DWD was host to the measuring campaigns LITFASS and LACE. Two LD-40 ceilometers are in permanent operation at Lindenberg. Their measurements were compared with those of a research lidar system of the lidar remote sensing group of the German Max Planck Institute for Meteorology participating at LACE, and a star photometer run by the Meteorological Observatory Lindenberg. In particular, a data averaging method for detecting cirrus clouds is introduced, and a comparison is made between the optical thickness of the planetary boundary layer as detected by the star photometer and ceilometer backscatter data from heights between 70 m and 1200 m.
